H07Z-K Power cable for Prefabricated Building

Cable Construction

Fine bare copper strands

Strands to VDE-0295 Class-5, IEC 60228 Class-5 BS 6360 cl. 5, HD 383

Cross-link polyolefin EI5 core insulation

H07Z-K is designed with stranded conductors and has cross-linked low smoke, no halogen (LSZH) insulation to ensure the cable is flexible and resistant to high temperatures.

Rated Voltage: 450/750 volts for higher voltage applications.

Temperature rating: 90°C rated for operation, improving the cable’s heat resistance.

flame-retardant acc. to EN 50265-2-1, IEC 60332.1

Features

Low smoke and non-halogen: it produces less smoke during combustion and does not release toxic gases, which improves safety in case of fire.

High temperature resistance: it can work stably in up to 90℃, suitable for wiring in high temperature environment.

Cross-linked insulation: improves the mechanical properties and chemical resistance of the cable.

For fixed wiring: suitable for fixed installations such as wiring inside distribution boards, control cabinets or inside equipment.

Flame retardant: conforms to IEC 60332.1 and other standards, with certain flame retardant ability.

Application Scenario:

Electrical appliances and meters: used to connect various electrical equipment and meters to ensure the safety of power transmission.

Power equipment: for internal or external connection of power equipment such as motors and transformers.

Automation devices: used for signal and power transmission between devices in automation systems.

Lighting systems: for the wiring of lamps and other lighting equipment, especially where safety and low-smoke halogen-free requirements need to be taken into account.

Energy-saving and environmentally friendly buildings: Because of its low-smoke and halogen-free characteristics, it is suitable for internal wiring in assembled buildings, container houses, and other buildings that have high requirements for environmental protection and safety.

Public and government buildings: In these places where strict safety standards are required, H07Z-K cables are widely used because of their excellent fire protection and low toxicity characteristics.

To summarize, H07Z-K power cables are widely used in industrial, commercial and residential environments where high quality and safe wiring is required due to their safety, environmental protection and high temperature resistance properties.
