Layer, outside are wrapped sealing sheath and the conducting wire that is formed, are mainly made of core, insulating layer, shielded layer and restrictive coating.Cable has
It occupies ground and space is few；Power supply safety is reliable, and electric shock possibility is small；Be conducive to improve the power factor of electric system；Operation,
Maintenance work is simple and convenient；Be conducive to beautifying city, there is many advantages, such as confidentiality, is widely used in living and producing
Every field.The effect of the coat layer of power cable is intrusion of the seal protection cable from introduced contaminants and moisture, prevents external force straight
Connect damage cable insulation.Cable cover(ing) layer material not only requires good airproof performance, anti-corrosive properties height, high mechanical strength, good flame resistance,
Should also have certain high temperature resistance.
Polyethylene is a kind of aggregated thermoplastic resin obtained of ethylene, because it has odorless, nontoxic, lower temperature resistance
Many advantages, such as energy is good, and chemical stability is good, and good corrosion resistance, water imbibition is small, and electrical insulating property is excellent, impact resistance is good, makes to gather
Ethylene becomes one of maximum cable material of usage amount, and existing cable cover(ing) layer material is mostly polythene material.With cable
The application environment of application in more areas, cable also becomes increasingly complex, thus, the requirement to the properties of cable is also got over
Come higher, the cable performance being prepared with single polythene material has been unable to meet the requirement of cable performance, uses cable
Polythene material, which is modified, to necessitate.
High temperature resistance is one of the property that cable needs to have, and is continuously increased with the range of cable application, electricity
Cable is also applied in more hot environments, thus, it is also higher and higher to the high temperature resistance requirement of cable, cable is used poly-
The high temperature resistance of vinyl material requires also higher and higher.A variety of methods are also used in the prior art to improve polythene material
Heat-resisting quantity, such as：Add inorganic filler and crosslinked method carried out to polyethylene, but due to the specific aim of raw material selection compared with
Difference or the influence for polyethylene polymerization degree control etc. factor, obtained modified polyethylene material high temperature resistance is not
There is the requirement for reaching anticipation or processability is good but heat-resisting quantity difference or the good processability of heat-resisting quantity are deteriorated, to serious
Affect the production and application of cable.
