Transparent composite PVC electric wire

Abstract

The invention particularly relates to a transparent composite PVC electric wire which comprises a wire inner core, a shielding layer, a composite insulating layer and a protective layer which are sequentially arranged from inside to outside along the radial direction. The composite insulating layer is coated with a thermosensitive color-changing layer, and the composite insulating layer and / or theprotective layer are / is prepared from the following raw materials in parts by weight: 100 parts of transparent polyvinyl chloride, 40-50 parts of polyurethane, 30-35 parts of a composite compatilizerand 8-12 parts of modified nanocellulose. The electric wire is high in stability and good in transparency durability, so that the discoloration condition of the thermosensitive color-changing layer can be conveniently observed by maintainers in time, a power supply can be quickly cut off when the temperature of the electric wire is too high due to faults such as short circuit, and economic loss and casualties caused by accidents such as fire disasters are avoided; meanwhile, the electric wire has good oxidation resistance, excellent temperature resistance and weather resistance, high strengthand excellent comprehensive performance.

Description

technical field [0001] The invention relates to the field of electric wire manufacturing, in particular to a transparent composite PVC electric wire. Background technique [0002] Wire and wire are indispensable and important materials in industrial and agricultural production and modern life. my country is the world's largest producer of wire and wire. The wire and wire industry occupies a very important position in my country's national economy. Wires and wires mainly include conductors, shielding layers, insulating layers and sheaths. The insulating layers or sheaths of wires and wires are made of opaque materials. If there is a failure or damage during use, it is very inconvenient to repair and maintain. Transparent Advanced wire insulation material helps to quickly troubleshoot and find damaged parts. The traditional transparent wire insulation layer has the problems of poor transparency and durability, easy to paste, fog and decrease transparency, and poor mechanical ...

AI Technical Summary

Problems solved by technology

The traditional transparent wire insulation layer has the problems of poor transparency and durability, easy to paste, fog and decrease transparency, and poor mechanical properties

At the same time, the wire has the function of transmitting signals and electric energy. During installation and long-term use, the wire may suffer from leakage or short circuit due to external force damage, aging of insulation and sheath, long-term load operation, environment and temperature, etc. However, due to the long distance of wire laying, some of them are still at high altitude, so it is difficult to find the fault location accurately and quickly, and it also causes relatively great difficulties for the detection and repair work.

Especially in the concentrated area where wires are laid, it is difficult to intuitively distinguish which wires are in normal operation, which wires are in leakage state, and which wires are in short-circuit outage state

Cannot effectively monitor the running status of the wires, and cannot guarantee the safe operation of the wires, resulting in short-circuit power failure or even fire accidents, resulting in economic losses and casualties
