Fire Resistant PVC Sheathed Copper XLPE Power Cable

Fire-resistant XLPE sheathed power cable

XLPE sheathed power cable

This kind of cable has a special fireproof coating, so it has excellent heat insulation and fireproof performance. It is mainly used for fire protection, surveillance and alarm equipment in modern urban buildings and places with strict safety requirements, such as emergency lighting, control and power circuits, power stations, fire alarm systems, underground tunnels, elevators, escalators and high-rise buildings.

When burning, this kind of cable will not diffuse and burn, will not emit halogen and low smoke, is non-toxic, can protect people from suffocation and corrosion, and can help the instrument avoid damage. Compared with PVC cables, XLPE cables have a higher long-term working temperature and a larger rated current. Under the same conditions, the XLPE insulation layer is thinner than that of PE or PVC, which not only improves the quality and performance of the cable, but also Reduced our production costs.

Physical and Electrical Characteristics

Product characteristics

1.1 The long-term allowable working temperature of the cable conductor does not exceed 70°C;

1.2. When short-circuited (the longest duration does not exceed 5 seconds), the maximum temperature of the cable conductor does not exceed 160°C;

1.3. The ambient temperature when laying cables should not be lower than 0°C.

2. Use characteristics

2.1 The maximum rated temperature of the cable conductor is 90°C, and the short-circuit time (the longest duration does not exceed 5S), and the maximum temperature of the cable conductor does not exceed 250°C.

2.2 The ambient temperature when laying the cable should not be lower than 0°C

2.3 The bending radius should be allowed when laying: single-core cables are not less than 15 times the outer diameter of the cable; multi-core cables are not less than 10 times the outer diameter of the cable
