Novel waterproof electric cable

Abstract

The invention provides a novel waterproof electric cable which comprises leads, a refractory material and a waterproof material, wherein insulation layers are arranged outside all leads, reinforcing ribs are arranged outside the insulation layers, protection layers are arranged outside the reinforcing ribs, reinforcing materials are arranged among all leads, the refractory material and the waterproof material are arranged outside the reinforcing material, inner protection layers are arranged in the refractory material and the waterproof material, and an outer protection layer is arranged outside the refractory material and the waterproof material. The novel waterproof electric cable is reasonable in structure and simple in design, is capable of effectively achieving heat resistance and protection due to the use of the refractory material, and is capable of effectively preventing moisture and water due to the arrangement of the waterproof material.

Description

technical field [0001] The invention belongs to the field of electrical technology, and in particular relates to a novel waterproof wire and cable. Background technique [0002] At present, general-purpose wires and cables generally include wires, inner sheaths, armor layers, and outer sheaths from the inside to the outside. Ordinary wires and cables do not have armor layers, and general wires and cables without armor layers often experience wear and tear during use. Broken, exposed, and leakage faults cause the conductors of the wires and cables to be very new, while the sheaths age ahead of time, which directly affects the service life and personal safety of the wires and cables, resulting in waste of resources. [0003] The fire-resistant wires and cables using traditional materials can only guarantee their normal power supply for a certain period of time under flame conditions, and cannot operate normally under the condition of being subjected to water showers and impact...

AI Technical Summary

Problems solved by technology

[0002] At present, general-purpose wires and cables generally include wires, inner sheaths, armor layers, and outer sheaths from the inside to the outside. Ordinary wires and cables do not have armor layers, and general wires and cables without armor layers often experience wear and tear during use. Broken, exposed, and leakage faults, the wires and cables are still very new, and the sheath is aging ahead of time, which directly affects the service life and personal safety of the wires and cables, resulting in waste of resources

[0003] The fire-resistant wires and cables using traditional materials can only guarantee their normal power supply for a certain period of time under flame conditions, and cannot operate normally under the condition of being subjected to water showers and impacts.

The reason is that under flame conditions, the high temperature resistant adhesive has lost its cohesiveness, the glass fiber cloth has lost its mechanical strength, and the bonding force between the mica scales has been quite loose. The insulation resistance of the structural refractory layer drops sharply, and the insulation resistance between the lines cannot be maintained, resulting in a short circuit

When there is a mechanical impact, the mica tape structure, which has been burned quite loosely, becomes more loose and falls off, and cannot maintain its insulation
