The semi-conductive shielding material with excellent mechanical performances, stripping performance, extrusion coking resistance, flame retardation performance, conductivity and temperature stability is obtained through reasonably designing the formula of the semi-conductive shielding material, adopting the coordination resistance and the most appropriate content ratio of all components and using a reasonable preparation technology.
Description
Technical field
The invention belongs to a kind of semiconductive shieldin material, specifically, more particularly to a kind of high pressure level power cable semiconductive screen
Cover material.
Background technology
The high pressure or ultra-high voltage cross-linking polyethylene-insulated power cable semiconductive shieldin material of 110kv and above, due to
Its working environment is in high voltage, in high current, it is desirable to which it can balance high electric field, voltage is kept stabilization, and this requires shielding
The particulate that the smoothness that material and insulating surface form surface is reached in ultra-smooth effect, i.e. per unit cm2 more than 25nm can not be more than
2.And due to shielding material contact copper core, it is under high currents, easily aging by metal catalytic, cause its service life short, this is just
It is required that shielding material has the ageing properties of resistance to metal catalytic higher, so as to extend its service life.Existing 35KV and following crosslinking
It is primary raw material that polyethylene-insulated power cable all uses ethylene vinyl acetate, adds general conductive black and paraffin to be produced
Processing, the need for properties of product far can not meet high pressure or ultra-high voltage cross-linking polyethylene-insulated power cable semiconductive shieldin material.
