Spiral anchor clamp for overhead lines | 685mm | 4xØ3mm | aluminium alloy

Spiral Anchor Clamp – a mechanical overhead power line fitting designed for gripping and anchoring conductors or cables in anchor assemblies and other suitable overhead line fastening points. The spiral construction wraps around a compatible conductor or cable and forms a stable mechanical connection.

The product is made of aluminum alloy. The total clamp length is 685mm, the construction consists of 4 wires, and the diameter of each individual wire is Ø3mm.

Application

The spiral anchor clamp is used in mechanical fastening systems for power transmission and distribution overhead lines. It is designed to surround a conductor or cable with spiral wires and form a reliable mechanical anchoring point.

The exact application of the product in a specific assembly depends on the type, diameter and construction of the conductor or cable, as well as on the other overhead line fittings used together with it.

Spiral construction

The product consists of several parallel spiral aluminum alloy wires. The construction consists of 4 individual wires.

The diameter of each wire is Ø3mm, while the total product length is 685mm. The spiral profile allows the wires to surround the conductor or cable over an extended contact area.

Aluminum alloy construction

The spiral anchor clamp is made of aluminum alloy. This material is lightweight and is used in various overhead power line fitting systems.

Before use, the material and dimensions of the specific conductor or cable must be evaluated to ensure that the selected clamp is mechanically compatible with it.

Suitable for

• Power transmission overhead line fitting systems
• Anchor fastening assemblies in power distribution networks
• Mechanical anchoring of compatible conductors or cables
• Overhead line pole fitting systems
• Mechanical fastening assemblies in substations and other energy infrastructure installations
• Outdoor electrical infrastructure where spiral anchoring is specified

Not suitable for

• Use without evaluating the mechanical loads of the complete fastening assembly

Practical application principle

Installation

Before installation, the condition of the clamp and integrity of the spiral wires must be checked, and it must be confirmed that the product is compatible with the dimensions and construction of the conductor or cable being used.

The spiral wires must be wrapped evenly according to their factory-formed geometry. The clamp shape should not be altered arbitrarily, individual wires should not be shortened, and the product should not be used with an incompatible conductor.
