Novel water-blocking moisture-proof power cable

Abstract

The invention discloses a novel water-blocking and moisture-proof power cable, and relates to the technical field of power cables. The cable specifically comprises an insulating core sleeve, a cable conductor is arranged in the insulating core sleeve, a conductor shielding layer is arranged between the outer side of the cable conductor and the insulating core sleeve, the outer side of the insulating core sleeve is coated with an insulator shielding layer, and the outer side of the insulator shielding layer is coated with an inner water blocking tape layer. The outer side of the inner water-blocking tape layer is coated with a flexible buffer layer, and the outer side of the flexible buffer layer is coated with an outer water-blocking tape layer. When cracks are generated, peculiar smells of the medicament and the asphalt are emitted through the cracks, insects and rats are effectively repelled, the asphalt is rapidly solidified when encountering a wet and cold environment in a tunnel, water is further prevented from permeating into the cable, the water-blocking and moisture-proof effects of the cable are enhanced, and meanwhile, the cable is prevented from being damaged. The multi-layer structure of the cable is reinforced through the protection armoring mechanism and the separation strips, and the stability between the internal structures of the cable is enhanced.

Description

technical field [0001] The invention relates to the technical field of power cables, in particular to a novel water- and moisture-proof power cable. Background technique [0002] Wire and cable are used to transmit electric (magnetic) energy, information and wire products that realize electromagnetic energy conversion. In the broad sense, wires and cables are also referred to as cables for short. In the narrow sense, cables refer to insulated cables, which can be defined as: a collection composed of the following parts; one or more insulated cores, and their respective possible coatings. The protective layer and outer sheath, the cable can also have additional uninsulated conductors, wire and cable as the main carrier of power transmission, widely used in electrical equipment, lighting lines, household appliances, etc., involving electricity, construction, communications, manufacturing and other industries are closely related to all sectors of the national economy.

AI Technical Summary

Problems solved by technology

[0003] Power cables mainly include four parts: core, insulation layer, shielding layer and protective layer. They are used in the power system to transmit and distribute high-power cables in the main line. They are usually used in urban underground power grids, and the environment in the cable pit is humid. , During paving, the surface of the cable rubs against the ground and tunnels, and the surface of the cable is often eaten by insects, ants, mice, etc., causing damage to the surface of the cable, reducing its water-blocking and moisture-proof effects, and affecting the stability of power transmission
