XLPE insulation flame retardant cable

XLPE insulation flame retardant cable     Applications: The product is mainly used in the installation of the places which require fire proof, such as high buildings, subways, nuclear power plants, important industries and mining enterprises. It can also be used in fire-fighting occassions. Meanwhile, it is the necessary cable for emergency power supply, fire pump, electric lift, and communication signal system.   Description of usage:
Long-run working temperature of PVC insulated cables can not be higher than 700 degrees Celsius. Long-run working temperature of XLPE insulated cable can not be higher than 900C
The temperature for wiring the cables can not be lower than 0C. Permissible curved radius (r) when wiring: 
Fireproof wires D<25mm: R≥4D D≥25mm: R≥6D (Douter diameter of the cable) 
Fireproof control cable: R≥10D 
Fireproof power cable: R≥10D   Technical properties:
The finished wires and cables can burn for 3 hours in the flame of 7, 500Cto 8000C, and meanwhile, they can go through the rated voltage, too. The fire proof property and its testing methods respectively meet stipulations of IEC331 and GB/19216. Flame retardant property is on complicance with IEC332-3. Fire proof control cable can go through the test voltage of 3.0kV for 5 minutes. Fire proof cable can go through the test voltage of 3.5kV for 5 minutes.
