Single-core flexible copper wire | 35 mm² | 450/750 V | red | PVC insulation | Lietkabelis H07V-K 35

H07V-K 35 is a single-core flexible copper wire with PVC insulation, 35 mm² cross-section and rated voltage of 450/750 V, red in colour. Designed for fixed electrical installation, laid in insulating conduits or trunking, and for wiring medium- and high-power equipment, appliance control and monitoring circuits. Sold by the metre, price given per 1 m, minimum order quantity – 10 m.

Main point:
When you need to connect a high-power load or wire the internal connections of a control panel, a thinner wire simply runs out of current-carrying capacity, while a rigid single-strand cable won't bend in a cramped panel space. H07V-K 35 resolves this conflict: a 35 mm² copper conductor, stranded from annealed copper wires, carries a large current, while the wire itself remains flexible enough to be laid in conduit or bent inside a panel without extra joints. The standardised 450/750 V insulation class allows the wire to be used in both power supply and control/monitoring circuits without separate matching for each purpose.

What makes H07V-K 35 useful?
It lets you carry high power through a single wire while still routing it conveniently along a complex path – unlike rigid single-strand conductors. The red insulation colour makes it easy to distinguish phases or circuits in panels with several wires, and the 35 mm² cross-section covers the needs of medium- and high-power equipment, machinery and automation systems in a single cable.

• Fixed installation – designed for laying in insulating conduits or trunking inside a building.
• Control and monitoring circuit wiring – suitable for automation and control circuit connections in panels.
• Medium- and high-power supply – the 35 mm² cross-section covers the power needs of equipment and appliances.
• Convenient installation in tight spaces – high flexibility allows bending the wire along a complex path without extra joints.
• Resistance to temperature fluctuation – insulation suitable from -30 °C to +70 °C and briefly withstands short-circuit loads.
• Verified insulation dielectric strength – the 2.5 kV test voltage ensures safe operation at the 450/750 V rating.

• Electrical distribution panels and boxes.
• Indoor building wiring.
• Connection of industrial equipment and machinery.
• Electrical wiring of automation and control systems.
• Installation of internal panel connections.
• Fixed installation, laid in surface-mounted or fixed insulating conduits or similar enclosed systems.

When building a new production facility, a route of about 24 m must be run in PVC conduit under the floor from the incoming electrical panel to the distribution box of a high-power machine. Ordering H07V-K 35 in the required 24 m quantity (above the 10 m minimum), the wire is laid along the entire conduit route; the -30…+70 °C operating range allows it to be used both in a heated production zone and in an unheated technical corridor, and the 450/750 V insulation safely withstands connection to a 400 V distribution panel.

• Install only in insulating conduits, trunking or similar enclosed systems – the wire is not intended for open outdoor laying.
• Carry out installation work at an ambient temperature of -5 °C to +40 °C – at lower temperatures the PVC insulation can crack when bent.
• Do not exceed +70 °C continuous operating temperature around the wire at the installation location.
• Use the red colour consistently to mark one phase or function, so the installation remains clearly identifiable.
• Before connecting to a power source, check that the terminal connections match the 450/750 V rated voltage and are properly insulated.
• Order the exact length required, taking the 10 m minimum order quantity into account, to avoid excess offcuts.
