Aluminum conductor power cable material with excellent mechanical property

Abstract

The invention discloses an aluminum conductor power cable material with an excellent mechanical property. The aluminum conductor power cable material is prepared from raw materials in parts by weight as follows: 30-40 parts of low-phenyl silicone rubber, 15-25 parts of nitrile rubber, 20-35 parts of metallocene polyethylene, 1.5-2.5 parts of tetramethyl thiuram disulfide, 1-2 parts of antimony dioxide, 0.5-0.6 parts of potassium ammonium dichromate, 0.3-0.8 parts of poly-p-nitrosobenzene, 1-2 parts of coumarone resin, 1.2-1.8 parts of coal pitch, 0.6-1.2 parts of chlorinated paraffin, 1-2 parts of tall oil, 1-2 parts of bis-dodecanol ester, 1-3 parts of pine tar oil, 10-20 parts of modified wheat protein, 5-15 parts of attapulgite, 50-75 parts of fumed silica, 8-16 parts of calcined clay, 0.5-1.5 parts of an ultraviolet absorber UV-531, 0.5-1.5 parts of an antioxidant 264 and 1-2 parts of zinc stearate. The aluminum conductor power cable material has good thermal stability and excellent extension resistance.

Description

technical field [0001] The invention relates to the technical field of cable materials, in particular to an aluminum core power cable material with excellent mechanical properties. Background technique [0002] Power cables are cable products used to transmit and distribute high-power electric energy in the main line of the power system, including 1-500KV and above various voltage levels and various insulated power cables. At present, the core materials of power cables are mainly copper and aluminum, but the copper density is high, the domestic resources are relatively scarce, and they are easily affected by the international market. Aluminum core power cables are more and more widely used, but the thermal stability of aluminum core power cable materials The resistance and extension resistance need to be improved urgently. Contents of the invention [0003] The invention provides an aluminum core power cable material with excellent mechanical properties, good thermal stab...
