High-overload resistant environmental-friendly wire

Abstract

The invention discloses a high-overload resistant environmental-friendly wire. The high-overload resistant environmental-friendly wire comprises a copper conductor and an insulation layer, wherein theinsulation layer wraps the copper conductor and comprises a temperature-resistant halogen free low smoke flame-retardant polyolefin insulation layer, a thermoplastic polyester elastic body insulationlayer, a polypropylene tape layer and a thin fluoroplastic insulation layer, the temperature-resistant halogen free low smoke flame-retardant polyolefin insulation layer wraps the copper conductor, the thermoplastic polyester elastic body insulation layer wraps the temperature-resistant halogen free low smoke flame-retardant polyolefin insulation layer, the polypropylene tape layer and the thin fluoroplastic insulation layer sequentially wrap the thermoplastic polyester elastic body insulation layer, and a polyvinyl chloride jacket layer warps the thin fluoroplastic insulation layer. The high-overload resistant environmental-friendly wire is simple in structure and reasonable in design, has favorable large-current resistant characteristic, also has favorable environmental-friendly performance and is not subjected to irradiation crosslinking, the insulation temperature-resistant performance reach 105 DEG C, special equipment is not needed to be replaced, the processing temperature of the material is wide in range, the production speed is fast, the high-overload resistant environmental-friendly wire can be yarded to form a circle after insulation extrusion, the irradiation crosslinking process is omitted, and the production efficiency is greatly improved.

Description

technical field [0001] The invention relates to electric wires, in particular to a high-overload-resistant environment-friendly electric wire. Background technique [0002] With the changes in the market, consumers have higher and higher requirements for products. In addition to the performance comparison of appearance, weight, flame retardancy, and environmental protection, the current promotion methods of marketers in the market are to use the wire quality speed tester the most. Carry out high-current short-time overload test, this test is also relatively easy for customers to accept at present. At present, the commonly used wires include PVC insulated wires with a temperature resistance of 70°C, thermoplastic heat-resistant 70°C halogen-free low-smoke flame-retardant polyolefin insulated environmental protection wires, and radiation cross-linked heat-resistant 105°C halogen-free low-smoke flame-retardant polyolefin insulation environmental protection Wire. The first two ...

Problems solved by technology

At present, the commonly used wires include PVC insulated wires with a temperature resistance of 70°C, thermoplastic heat-resistant 70°C halogen-free low-smoke flame-retardant polyolefin insulated environmental protection wires, and radiation cross-linked heat-resistant 105°C halogen-free low-smoke flame-retardant polyolefin insulation environmental protection Wire. The first two have low temperature resistance and poor overload resistance. The latter has better overload resistance after irradiation crosslinking, but due to low production efficiency and low cost performance, it cannot meet the needs of consumers.
