SHARK SH0506 – a sealed, re-openable gel cable joint designed for up to five-core 0.6/1 kV electrical cables with conductor cross-sections of 1.5–6 mm². The non-toxic silicone gel inside the joint insulates electrical connections and forms a protective barrier against moisture, water and dirt. The included five-pole insulated terminal block with screw clamping allows copper, aluminium and copper-to-aluminium conductors to be connected. The blue polypropylene housing, compact 146 × 55 × 35 mm dimensions and IP68 degree of protection allow the joint to be used in underground, above-ground, outdoor and cable-duct installations. The construction can be reopened, allowing the connection to be inspected or adjusted without replacing the insulating gel.

Key point:
Connecting electrical cables in demanding environments requires not only a reliable electrical contact, but also protection against water, moisture and contaminants. A conventional junction box with terminals is not always suitable for underground installations or locations exposed to water. SHARK SH0506 solves this problem by combining an insulated five-pole terminal block, protective housing and silicone sealing gel in one construction. The cables are connected with screw terminals, while the gel in the closed joint surrounds the connection area and isolates it from the environment. If necessary, the joint can be reopened – without removing resin or adding new gel.

⚡ Spark: Phase, why do you need a gel joint? Can't cables simply be connected in a standard watertight box?

⚙ Phase: They can, provided that the box and its cable entries are suitable for the installation conditions. However, a gel joint has an additional advantage – the connections are not only enclosed in a housing, but also surrounded by insulating silicone gel. This creates a barrier against water and dirt. Most importantly, the SHARK joint is not a one-time resin-filled joint. If the contact later needs to be checked or the connection changed, the housing can be opened and closed again without adding more gel.

Why is this gel cable joint useful?
SHARK SH0506 combines a five-pole electrical connection, silicone insulation and protective housing in one kit. This allows up to five cable conductors to be connected, protected from moisture and still accessible in the future. Compatibility with copper and aluminium conductors, IP68 protection, a UV-resistant housing and the possibility of reopening make the joint a practical solution for more demanding electrical installation conditions.

When installing outdoor area lighting, it may be necessary to connect two five-core electrical cables on an underground cable route. If 0.6/1 kV cables are used with conductor cross-sections of 1.5–6 mm² and an outer diameter within the Ø11–19 mm range, the SHARK SH0506 gel joint can be used for the connection. The cable conductors are prepared and connected in the included five-pole screw terminal block. The terminal block is placed inside the gel-filled housing, the cables are arranged according to the joint construction and the housing is closed. The silicone gel surrounds the connection area and protects it from moisture. If an inspection is later required, the joint can be opened, the contacts accessed and the housing closed again after the work is completed. Mechanical strain relief of the cables must be provided separately.

• Electrical work must be carried out by a qualified specialist. Disconnect the power supply before installation and verify that no voltage is present.
• Select suitable cables. The joint is intended for 0.6/1 kV cables with connected conductor cross-sections of 1.5–6 mm² and a cable outer diameter of Ø11–19 mm.
• Conductor preparation. Remove the outer cable sheath and conductor insulation only as much as necessary for a reliable connection according to the construction of the supplied terminal block.
• Screw contacts. Conductors must be correctly inserted and clamped in the terminal block. Loose, partially inserted or insufficiently clamped conductors are not permitted.
• Cu and Al conductors. The terminal block is suitable for copper, aluminium and Cu/Al connections. When joining different metals, the contact surfaces must be properly prepared and the correct connection method followed.
• Core identification. When connecting a five-core cable, correct correspondence of phase, neutral and protective conductors must be maintained according to the electrical diagram.
• Terminal block position. After connecting the conductors, place the insulated terminal block inside the joint housing so that its position does not interfere with closing the housing.
• Preservation of gel insulation. The sealing gel does not need to be mixed or additionally prepared. When closing the joint, ensure proper distribution of the gel around the connection area.
• Closing the joint. The housing must be fully closed and the cables arranged so that they do not interfere with the sealing area.
• Mechanical cable fixing. SH0506 does not have an integrated strain relief system, so the cables must be fixed so that tensile forces are not transferred to the terminal block.
• Underground installation. The cable joint must be protected from mechanical damage and installed in accordance with requirements for underground cable routes.
• Outdoor use. The UV-resistant housing is intended for above-ground installations, but the characteristics of the cables and additional fixing elements must also be suitable for outdoor environmental conditions.
• Water exposure. The IP68 protection characteristic applies to a properly installed and fully closed joint. No foreign objects that could prevent complete closure may remain in the connection area.
• Reopening. Disconnect the power before opening the joint. After modifying the connection, the gel must remain properly distributed and the housing undamaged.
• Operating temperature limits. The housing operating temperature is from −20 °C to +90 °C. The connection must operate within the temperature ratings of all system components.
• Inspection after installation. Before energising, check conductor connections, protective circuit continuity and the required electrical installation tests.

⚡ Phase tip:
When selecting a gel joint, it is important to consider not only the conductor cross-section but also the overall outer diameter of the cable. For example, two five-core cables from different manufacturers with the same conductor cross-section may have different outer diameters. SH0506 is intended for Ø11–19 mm cables, making this one of the most important selection parameters. During installation, also provide separate mechanical fixing of the cable: the gel provides insulation and the screw terminals provide electrical contact, but they must not be used to withstand tensile cable loads.

Quick selection guide

⚡ Spark: How is a gel joint different from a conventional watertight cable box?
⚙ Phase: The silicone gel inside the gel joint directly surrounds the electrical connection and fills the cavities around it. In a conventional watertight box, protection generally depends on the sealing of the housing and cable entries. The SHARK joint combines housing construction with gel insulation.

⚡ Spark: Can this joint be buried underground?
⚙ Phase: Yes, SH0506 is also intended for underground cable connections. Gel insulation and the water protection characteristic allow it to be used in environments exposed to moisture. Suitable mechanical protection for the cables and joint must also be provided on underground routes.

⚡ Spark: Does IP68 mean that water cannot reach the electrical connection?
⚙ Phase: IP68 means a high level of protection against the ingress of dust and water under specified test conditions. In the SHARK joint, the electrical connection is additionally insulated by silicone gel. To ensure proper protection, cables of the specified size must be used and the housing must be fully closed.

⚡ Spark: Can the gel joint be opened after installation?
⚙ Phase: Yes. The SHARK Classic construction is re-openable. The silicone gel does not harden like resin, so after disconnecting the power, the terminal block can be accessed, the connection inspected or modified, and the joint closed again.

⚡ Spark: Does the gel need to be replenished after opening?
⚙ Phase: No. During normal reuse, the gel does not need to be replenished. It is important that it remains clean and properly distributed when the housing is closed.

⚡ Spark: Can a copper cable be connected to an aluminium cable?
⚙ Phase: Yes. The included tinned aluminium terminal block is intended for copper, aluminium and Cu/Al connections. It is important to prepare the conductors correctly and ensure proper screw clamping.

⚡ Spark: Is this joint suitable for a five-core 5 × 6 mm² cable?
⚙ Phase: Yes, 6 mm² falls within the 1.5–6 mm² conductor cross-section range and the terminal block has five poles. However, the overall cable outer diameter must also be within the Ø11–19 mm range.

⚡ Spark: What does the 0.6/1 kV marking mean?
⚙ Phase: This is the rated insulation voltage designation for cables. 0.6 kV means the rated voltage between conductor and earth, while 1 kV means the rated voltage between conductors. This type of joint is used for electrical cable connections of the corresponding voltage class.

⚡ Spark: Does the gel harden after closing the joint?
⚙ Phase: No. The SHARK joint uses flexible silicone gel that retains its structure and allows the joint to be reopened. There is no need to mix it or wait for it to cure.

⚡ Spark: Can the joint be used for outdoor electrical lighting?
⚙ Phase: Yes. It can be used for outdoor lighting cable connections when cable voltage, number of conductors, cross-section and outer diameter correspond to the joint specifications. The UV-resistant housing and gel insulation provide additional protection in outdoor installations.

⚡ Spark: Are terminals included inside the joint, or must they be purchased separately?
⚙ Phase: The five-pole insulated screw terminal block is included. The set also includes the pre-filled gel joint, fixing ties and installation instructions.

⚡ Spark: Does this joint protect the cable from being pulled out or strained?
⚙ Phase: No. SH0506 does not have an integrated cable strain relief system (SRS). The cables must therefore be mechanically fixed so that tensile force is not transferred to the terminal block or connection area.
