Single-core DC shielding waterproof, fireproof, mouse-proof and ant-proof power flexible cable

Abstract

The invention discloses a single-core DC shielding waterproof, fireproof, mouse-proof and ant-proof power flexible cable comprising a wrapping tape, an insulating layer, a shielding layer, a waterproof layer, a fireproof belt, an oxygen isolating material and an outer sheath that are successively arranged on the outer side of a conductor from the inside to the outside. The outer sheath contains 18% to 30% of EVA, 6% to 10% of LLDPE, 5% to 10% of POE, 3% to 6% of composite flame retardant, 22% to 30% of aluminum hydroxide, 22% to 30% of magnesium hydroxide, 0.3% to 0.6% of antioxidant-1, 0.2% to 0.5% of antioxidant-2, 2.0% to 5.0% of compatilizer, 0.5% to 0.8% of processing agent, 0.5% to 1.0% of UV absorber, 0.5% to 1.2% of silane coupling agent, 0.3% to 1.0% of M-17 environment-friendly mouse-proof agent, 0.3% to 0.8% of S-07 environment-friendly ant-proof agent, and 0.5%to 1.0% of essence. The single-core DC shielding waterproof, fireproof, mouse-proof and ant-proof power flexible cable solves a problem that a conventional cable is poor in waterproof, fireproof, mouse-proof and ant-proof effect, greatly reduces the possibility of cable failure, and provides stable guarantee for power and signal transmission and vehicle operation.

Description

technical field [0001] The invention relates to a flexible power cable, in particular to a single-core DC shielded waterproof, fireproof, rodent and ant-proof power flexible cable. Background technique [0002] With the rapid development of the national economy, the use of cables and the density of laying are getting higher and higher. In recent years, fires caused by electricity have increased year by year, and fires caused by wires and cables account for a considerable proportion. In the fire, the "secondary disaster" caused by the release of corrosive and toxic gases and the large amount of smoke caused by the spread of the cable fire has attracted people's attention. In the event of a fire, there will be a lot of water at the fire fighting site, so waterproofing is equally important. At the same time, wire and cable sheath materials are not only damaged by oxygen, heat, light, force, chemical erosion and other environmental damage during use, but also by termites, mice ...

AI Technical Summary

Problems solved by technology

At the same time, wire and cable sheath materials are not only damaged by oxygen, heat, light, force, chemical erosion and other environmental damage during use, but also by termites, mice or hares and other organisms, which will cause power outages and telecommunications interruptions. , The phenomenon of operation stop and misoperation after the wiring of the computer is damaged by rats occurs from time to time

Due to short-circuit accidents caused by wires and cables being eaten by rats, fires and other hazards are caused, causing serious losses to social activities and the national economy.
