Appendix: Cable Properties
1. The cable is characterized by anti-acid and anti-alkali, anti-oil, and anti-aging, etc; Shielded type is anti-interference.
2. Low smoke and low halogen wire and cable has low fuming amount, releasing little hydrogen chloride, so on fire, it cause little corrosion, danger and damage to equipment, people and environment.
3. Cross-linked polyethylene insulating cable has large current capacity; and it is light and handy in structure. It is not restricted by drop. Cable short time over loading working temperature should not exceed 130℃; Total short circuit temperature not exceed 250℃; Lasting for no more than five seconds.
4. fire-resistant cable can work for over 90 minutes under 750℃-900℃; the fireproof properties test accords with GB12666.6 standards.
