HPVC-C power cable protection tube

Abstract

The invention discloses an HPVC-C power cable protection tube, which comprises a cable and a triangular supporting layer, wherein the cable is composed of copper core wires, alloy layers and a filling layer; the copper core wires are coated with the alloy layers; the plurality of alloy layers are provided with the filling layer; the filling layer is tangent to the inner side of the triangular supporting layer; the gap between the filling layer and the triangular supporting layer is provided with heat insulation blocks; and a metal mesh layer, an inner insulating layer, an inner shielding layer, an outer insulating layer, an outer shielding layer and a protective layer are sequentially arranged outside the triangular supporting layer. As a steel wire mesh, rubber and hard nano silica gel particles are compound to form the triangular supporting layer, a good resistance role can be placed in the case of strong impact; as the power cable tube is provided with the inner shielding layer and the outer shielding layer, effects on shielding a magnetic field generated by current are good, and operation of surrounding equipment is not influenced; and the HPVC-C power cable protection tube has the advantages that the structure is simple, the anti-impact ability is strong, the magnetic field shielding effects are good, and wide popularization and application can be carried out.

Description

【Technical field】 [0001] The invention relates to the technical field of power cable protection, in particular to the technical field of power cable protection tubes. 【Background technique】 [0002] In daily life, power cables are widely used in various industries and occasions. Some are placed in harsh environments, such as buried in the ground, the underground environment is humid, or exposed outdoors, exposed to wind and sun, etc., are greatly affected. The life of the cable protection tube is shortened; with the progress of the times, the requirements for the cable protection tube are getting higher and higher, and the magnetic field generated by the electricity is required not to affect the surrounding equipment. The existing ordinary power cable tube can no longer adapt to this 1. Requirements: During the moving and installation process of the cable tube, it is often subject to sudden impact such as impact, and the dead power cable will be damaged inside, which will af...

[0002] In daily life, power cables are widely used in various industries and occasions. Some are placed in harsh environments, such as buried in the ground, the underground environment is humid, or exposed outdoors, exposed to wind and sun, etc., are greatly affected. The life of the cable protection tube is shortened; with the progress of the times, the requirements for the cable protection tube are getting higher and higher, and the magnetic field generated by the electricity is required not to affect the surrounding equipment. The existing ordinary power cable tube can no longer adapt to this 1. Requirements; During the moving and installation of the cable tube, it is often subject to sudden impact such as impact, and the inside of the power cable that will die will be damaged, which will affect the use effect
