Example Embodiment

[0014] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0015] Such as figure 1 As shown, this embodiment provides a waterproof cable, which includes a conductor 1, an insulating layer 2, a waterproof layer 3, and a sheath layer 4 arranged in sequence from the center to the outside. The insulating layer 2 wraps the conductor 1, and the insulating layer The layer 2 is a polyvinyl chloride insulating layer, the waterproof layer 3 wraps the insulating layer 2, the waterproof layer 3 is a polyethylene waterproof layer, the sheath layer 4 wraps the waterproof layer 3, the sheath layer 4 is the PVC sheath layer. The number of the conductors 1 is seven, each of the conductors 1 is wrapped with the insulating layer 2, and the insulating layer 2 collectively wraps the waterproof layer 3. The insulating layer 2 is wrapped with mica tape. The insulating layer 2 and the waterproof layer 3 are filled with mi...

Abstract

The invention provides a waterproof cable which includes conductors, insulating layers, a waterproof layer and a protective layer, which are arranged from the center to the outside sequentially. The insulating layers wrap the conductors and are polyvinyl chloride insulating layers. The waterproof layer wraps the insulating layers and is a polyethylene waterproof layer. The protective sleeve layer wraps the waterproof layer and is a polyvinyl chloride protective layer. The waterproof cable is reasonable in structural design and greatly improved in safe protection performance; and a longer period of normal time of the cable can be ensured and the structural stability of the conductors in the cable can be improved so as to prevent the cable from being affected by an external force and deformed in a use process and thus the normal service life of the cable is prolonged.

Description

technical field [0001] The invention relates to a cable, in particular to a waterproof cable. Background technique [0002] During the use of the cable, if the outer insulation layer and other fireproof layers of the cable are damaged or aged and the conductor in the center of the cable leaks, it will cause a safety hazard. When the conductor in the center of the cable is flooded, it is more likely to The safety of the cable is extremely important to cause irreparable harm to the user or other personnel. The above-mentioned problems should be prevented and resolved in the design, production and use of the cable. Contents of the invention [0003] The purpose of the present invention is to provide a waterproof cable to solve the problem that the conductor in the center of the cable leaks due to damage or aging of the insulating layer and other fireproof layers outside the cable, which will cause potential safety hazards, so that the safety protection performance of t...
