Waterproof and fireproof cable structure

Abstract

The invention discloses a waterproof and fireproof cable structure. The structure comprises an outer sheath. The outer sheath wraps a waterproof material structure layer. A surface of the waterproof material structure layer is provided with a silk screen. The silk screen carries out injection molding on the waterproof material structure layer. An antistatic layer is arranged in the waterproof material structure layer and the waterproof material structure layer is connected to the antistatic layer through a non-woven material layer. The non-woven material layer is winded around and arranged on the antistatic layer. A filling layer is arranged in the antistatic layer. The filling layer is connected to the antistatic layer in a sealing mode and an internal surface is provided with a compression resistance body. The compression resistance body and the filling layer are fixedly connected. An inner sheath is arranged in the filling layer. The inner sheath is fixed to the filling layer. In the invention, fireproof performance of a cable is increased, construction difficulty is reduced, operation is convenient, a suitable scope is large, simultaneously a good antistatic ability is possessed, a problem that transmission is interfered is reduced, and a usage intensity is increased.

Description

technical field [0001] The invention relates to a cable structure, in particular to a waterproof and fireproof cable structure. Background technique [0002] In the existing fireproof cables, the structure mainly includes 1 to 5 copper cores, each copper core is wrapped with a mica layer, and then 1 to 5 copper cores are wrapped in the copper tube, and the copper tube is wrapped with a mica layer. The inner wall is provided with a mica layer. Such a fireproof cable mainly has the following disadvantages: 1. The fireproof performance is poor, and short circuits are prone to occur, resulting in the inability to transmit current; The tube makes the construction difficult when installing at the turning position, and at the same time, there are certain defects in the functional structure, which cannot better achieve the use effect. Contents of the invention [0003] The technical problem to be solved by the present invention is to overcome the above problems and provide a wate...
