Is YJV cable copper core or aluminum core? Low smoke halogen-free flame retardant of Zhengzhou first cable Co., Ltd

  　　  What are the characteristics of low smoke halogen-free flame retardant cables of Zhengzhou first cable Co
, Ltd
There are many kinds of wires and different uses
Low smoke halogen-free flame retardant cables have the characteristics that other cables do not have
Let me introduce them to you today 1
The tensile strength of low smoke halogen-free flame retardant wire is greater than that of ordinary PVC wire
The tensile strength of ordinary PVC wire will be greater than 1
05kgf/mm2, and the tensile strength of low smoke halogen-free flame retardant cable will be greater than 1
2kgf/mm2 　　2
Low smoke halogen-free flame retardant cable has good weather resistance and good softness 3
Low smoke halogen-free flame retardant cable also has non mobility, so this kind of wire does not need to add plasticity and will not have mobility
When burning, it will not produce toxic black smoke, and the volume resistivity is relatively high
PVC wires are generally 1012 ~ 1015 & omega/ Cm3, low smoke halogen-free wire has high electrical resistance
PVC wires are generally resistant to more than 10kV, but low smoke halogen-free wires can reach more than 15kV, with high elasticity and viscosity
