Halogen-Free Low-Smoke Flame-Retardant Fire-Resistant Power Cable
Introduction to LSZH Cable
LSZH cables produce a very small amount of smoke in the case of flame burning, and the released gas contains no halogen elements and is non-toxic. When a fire occurs, it can greatly reduce the harm to equipment, equipment and the human body.

LSZH Cable Features
1. An environmentally friendly cable that is made of a compound that does not contain halogen, lead, cadmium, chromium, mercury and other environmental substances, and does not emit toxic fumes when burned. When a fire occurs, the spread speed is slow, the smoke concentration is low, the visibility is high, the emission of harmful gases is small, and the low halogen and halogen-free characteristics make the cable material greatly improve the resistance to aging, ultraviolet and other radiation, thereby extending the cable Life.
2. It has all the characteristics of halogen-free, low-smoke and flame-retardant power cable. It burns in a flame environment of 800℃ and below, and can ensure that the power is over 180min, which is twice as long as the conventional fire resistance time and is more safe.
Product technical performance
1. The maximum temperature of the power cable conductor in normal operation and the maximum temperature when short-circuited (the longest duration does not exceed 5s); the low-smoke halogen-free polyvinyl chloride insulation is 70℃, and the maximum temperature when short-circuited does not exceed 160℃; cross-linked polyethylene The insulation is 90℃, the thermoplastic low-smoke halogen-free polyolefin insulation is 80℃, and the maximum temperature does not exceed 250℃ when short-circuited. The radiation cross-linked polyethylene insulation is 105℃ and 125℃, and the maximum temperature when short-circuit does not exceed 250℃.
2. The installation conditions and allowable continuous current carrying capacity of the low-smoke and halogen-free cables are the same as those of the corresponding non-low-smoke and halogen-free cables.
3. The cables and wires have low smoke, halogen-free, flame-retardant and fire-resistant properties when they are burned.
