Abstract

The utility model discloses an automatic-temperature-control heating cold-resistant electric wire which is composed of a reinforcing core, a silicon rubber insulation layer, a belting layer, a copper tape armor layer, a tinned copper wire shielding layer, a butyronitrile insulation layer, an aluminum tape armor layer, an ethylene propylene rubber insulation layer and a chloroprene rubber sheath layer. The silicon rubber insulation layer is arranged as the center layer of the electric wire. The reinforcing core is extruded inside the silicon rubber insulation layer. The silicon rubber insulation layer is coated with the belting layer. The belting layer is coated with the copper tape armor layer. The copper tape armor layer is coated with the tinned copper wire shielding layer. The tinned copper wire shielding layer is coated with the butyronitrile insulation layer. The electric wire has high bending resistance and good heat dissipation effect, is resistant to high temperature and cold, is convenient to transport, and has the advantages of strong antioxidant capacity, high tensile strength and low temperature in a laying environment.

Description

A kind of temp auto-controlled heating cold-resistant electric wire

Technical field

The utility model belongs to electric wire field, relates in particular to a kind of temp auto-controlled heating cold-resistant electric wire.

Background technology

At present, along with Chinese society expanding economy, electric wire electric wire consumption increases rapidly, the quality requirement of electric wire is also constantly improved, such as the electric wire using in the field such as computer, machine room, high and low temperature resistance to electric wire, pull resistance, thermal diffusivity, cold-resistant high temperature resistant and non-oxidizability aspect require all high especially.

Utility model content

In order to overcome the defect of above-mentioned prior art, the purpose of this utility model is to provide a kind of high temperature resistant, cold-resistant, and non-oxidizability is strong, lays the temp auto-controlled heating cold-resistant electric wire that temperature environment is low.

The utility model takes following technical scheme to realize: a kind of temp auto-controlled heating cold-resistant electric wire, it is by strengthening core, silicone rubber insulation layer, belting layer, copper strips armour, tinned copper wire screen, butyronitrile insulating barrier, aluminium strip armour, ethylene propylene rubber insulated layer and chloroprene rubber sheath layer composition, described silicone rubber insulation layer is set to the central core of this electric wire, described silicone rubber insulation layer inside is extruded with a strengthening core, outside described silicone rubber insulation layer, wrap up one deck belting layer, outside described belting layer, wrap up one deck copper strips armour, outside described copper strips armour, wrap up one deck tinned copper wire screen, outside described tinned copper wire screen, wrap up one deck butyronitrile insulating barrier, described tinned copper wire screen inside is provided with 16 aluminium alloy conductors, described butyronitrile insulating barrier inside is provided with 24 aluminium alloy conductors.

The utlity model has in sum following beneficial effect: this kind of electric wire resistance to bend(ing) is strong, good heat dissipation effect is high temperature resistant, cold-resistant, and convenient transport also has non-oxidizability strong simultaneously, and pull resistance is strong, lays the advantage that temperature environment is low.
