Gradually it is down to room temperature.
The present invention has advantages below compared with prior art：
1）Conventional cross-linking polyethylene materials do not have fire resistance so that with the cable of this material manufacture in case of fire
Fluidised form is easily melt into, deflecting turns into combustion adjuvant, so as to limit the use occasion of this material converted products.And in material of the present invention
25-30 parts of fire retardant is added so that material has certain fire resistance, improves the safe application performance of cable, while resistance
Combustion agent enables that fire retardant is completely dispersed in other materials and merges with the specific proportions collocation of remaining auxiliary material, and is routinely crosslinked poly-
Even if fire retardant will not also be merged during vinyl material adds instant component.
2）The existing cross-linking polyethylene materials with fire resistance are generally irradiated crosslinking low-smoke and halogen-free material, with higher
Density, while because the addition of a large amount of flame-retardant compositions causes that the insulation specific insulation of material is suitable with PVC material.And material of the present invention
Material insulation specific insulation can be higher by 10 compared with PVC insulation specific insulations3。
The beneficial effects of the invention are as follows：Using the cable of the insulating materials, with insulaion resistance higher, equal is fire-retardant
Performance, relatively low coefficient of friction, excellent sunlight resistance energy.
