Information Source:Henan Huadong Cable Co., Ltd Release date:2014-02-20

1 low voltage XLPE cable (XLPE), since the mid ninety's into the application of rapid development, has been with the polyvinyl chloride (PVC) market share accounted for half of each cable. XLPE cable with PVC cable compared, carrying capacity is higher, overload ability, long service life (PVC cable environment better thermal life is generally 20 years, while the XLPE cable thermal life is generally 40 years); PVC combustion would decompose and release a lot of smoke and toxic gases, while the XLPE combustion does not produce halogen toxic gas, recognized superiority of XLPE cable is for design and application departments.

2 common PVC wire and cable (insulation and sheath) combustion delay fired rapidly, fueling the fire, 1 ~ 2min the loss of power supply, its combustion decomposition releases black smoke is blinding, cause respiratory and evacuation difficulty. More serious is, PVC combustion will release hydrogen chloride (HCL) and dioxins and other toxic corrosive halogen gas, is a major cause of death induced in fire (fire death factors accounted for 80%), and a dilute hydrochloric acid guide shaped electric membrane attached to the electrical equipment, severely reducing the insulating properties the formation of two natural disasters, difficult to clean.
