Environment-friendly clean prefabricated branch cable and manufacturing method thereof

Abstract

The invention discloses an environment-friendly clean prefabricated branch cable. The environment-friendly clean prefabricated branch cable comprises a main cable body, branch cable bodies, a C-shaped sleeve and a die-pressed branch connector, wherein a main cable body silicone rubber insulating layer and a main cable body silicone rubber outer sheath are arranged outside a conductor of the main cable body in sequence, a branch cable body silicone rubber insulating layer and a branch cable body silicone rubber outer sheath are arranged outside a conductor of each branch cable body in sequence, talcum powder with a separant and non-woven fabric in which the main cable body is wrapped are arranged between the main cable body silicone rubber insulating layer and the main cable body silicone rubber outer sheath, the portion, where the conductor of the main cable body is connected with the conductor of each branch cable body, of the main cable body silicone rubber outer sheath, the portion, where the conductor of the main cable body is connected with the conductor of each branch cable body, of the main cable body silicone rubber insulating layer, the portion, where the conductor of the main cable body is connected with the conductor of each branch cable body, of the corresponding branch cable body silicone rubber outer sheath, and the portion, where the conductor of the main cable body is connected with the conductor of each branch cable body, of the branch cable body silicone rubber outer sheath are stripped, and the conductor of the main cable body and the conductors of the branch cable bodies are connected in a pressed mode through C-shaped clips with convex ridges.

Description

technical field [0001] The invention relates to the field of wires and cables, in particular to an environmentally friendly and clean prefabricated branch cable and a manufacturing method. Background technique [0002] With the rapid development of modern society, high-rise buildings are becoming more and more popular. In the electrical design of high-rise building power distribution system, power supply reliability, engineering economy and construction convenience are becoming more and more important. The branch cable came into being. The contact resistance of the branch joint of the branch cable is extremely small, and it is not affected by thermal expansion and contraction and slight vibration. It has excellent shock resistance, air tightness, waterproof, maintenance-free, and its conductor performance and insulation performance. The physical and mechanical properties of the material are higher than the requirements of GB / T12706. The branch connector connects the conduct...
