Operation character

Fire-resistant property

(1) According to national standards, fire-resistant wire and cable fire test method characteristic

test, according to GB12666.6

Class A, burn in fire with flame temperature 950°C, apply voltage of 750V between phase and

phase and between phase and outer sheath,it should be able to withstand for 90min without

breakdown.

Class B, bun in fire with flame temperature 750-800°C, apply voltage of 750V between phase

and phase and between phase and outer sheath,it should be able to withstand for 90min without

breakdown.
