Abstract

The invention discloses a fluorinated ethylene propylene copolymer tensile cable, comprising: at least one conductor core, an insulating layer wrapped around the conductor core, a shielding layer wrapped around the insulating layer, The sheath layer wrapped around the shielding layer; the sheath layer includes an inner sheath, an inner lining layer, an armor layer and an outer coating layer; the outer coating layer is made of modified fluorinated ethylene propylene copolymer The modified fluorinated ethylene propylene copolymer material is prepared from the following raw materials in parts by weight: 20-30 parts of basalt fiber, 8-12 parts of modifier, 20-30 parts of poly Propylene, 35-45 parts of fluorinated ethylene-propylene copolymer, 0.3-0.8 parts of coupling agent, 0.1-0.3 parts of cross-linking agent; The fluorinated ethylene propylene copolymer material is used as the outer layer in the cable sheath layer, which improves the tensile resistance of the fluorinated ethylene propylene copolymer cable, makes the fluorinated ethylene propylene copolymer cable better adaptable, and has a wider application range.

Description

technical field [0001] The invention relates to the field of cables, in particular to a fluorinated ethylene propylene copolymer tensile cable. Background technique [0002] The cable is made of one or more wires twisted to form a conductor core, and then a corresponding insulating layer is applied to the conductor, and a sealed sheath is formed on the outside. It is mainly composed of a core, an insulating layer, and a shielding layer. and sheath layer. The cable occupies less ground and space; the power supply is safe and reliable, and the possibility of electric shock is small; it is beneficial to improve the power factor of the power system; the operation and maintenance work is simple and convenient; it is beneficial to beautify the city and has many advantages such as confidentiality. It is widely used in life. and all areas of production. The performance of the cable sheath is one of the main factors that determine the environment in which the cable is used. At the ...
