Power cable test, found abnormal processing time.

The cable channels are kept dry to prevent the power cable from getting wet, causing insulation to drop and causing a short circuit.

Regular cleaning of power cables is the accumulation of dust, preventing the spontaneous combustion of dust from causing fire, cable products.

Strengthen the switch and protection calibration of the power cable circuit to ensure reliable motion.

Lay the cable and heat pipe to maintain a sufficient distance of not less than 0.5 m, control cable; power cable not less than 1 m control cable and power cable should be divided into slots, layers and overlapping layers between the separation devices, no. If the cable is not fired, the insulation shall be taken.

Install a fire alarm device to detect the fire in time to prevent the cable from catching fire.

Take fire prevention measures. Fire protection measures for power cables:

The cable wrapped by the insulation material of the power cable. When the cable is on fire, the package is a heat-insulating flame-retardant material and burns on fire. If the cable is fired, the lack of oxygen combined with the body can cause the fire to self-extinguish, preventing the fire from spreading to the body's bandages.

The power cable passes through the wall, the bottom plate, the shaft hole and the refractory material are tightly sealed to prevent the cable fire, the spread of high temperature smoke and the spread of the fire.

Fire-resistant paint on the surface of the power cable paint.

The fire belt will prevent burning of part of the power cable windings.

A heat-resistant fireproof board is arranged between the cable layers to prevent suffocation between the cable layers and expand fire protection.

Set segmentation and fire doors on the cable TV channel to prevent the power cable from burning and expanding.
