CN203150219U - Super-soft special excitation line - Google Patents

Abstract

The utility model discloses a super-soft special excitation line. The super-soft special excitation line includes a line core; 180 DEG C-level polyester-imide enameled round copper wires are stranded so as to form the line core; the outer diameter of the line core is not larger than 6.5 mm; the exterior side of the line core is tightly wrapped with a wrapping layer; the exterior side of the wrapping layer is wrapped with a glass fiber-braided sheath which is coated with organosilicon paint; and the outer diameter of a finished line is not greater than 7.5 mm. The super-soft special excitation line of the utility model has the advantages of high temperature resistance, high tensile strength and light heat-resisting stability; and frequent bending will not affect the transmission effect of the super-soft special excitation line.

Description

Super soft special excitation wire

technical field

The utility model relates to aerospace technology, in particular to a high-tensile, high-temperature-resistant, super-soft special excitation wire matched with civil aviation engines.

Background technique

With the rapid development of my country's electronic technology, its requirements for matching wires and cables are getting higher and higher. The existing varieties of wires and cables can no longer fully meet the needs of matching. Anti-electromagnetic interference, anti-ultraviolet and stable transmission quality have put forward higher requirements. High requirements are put forward for the use of vehicle-mounted and ship-borne electronic equipment. At present, there is no relevant cable at home and abroad that can meet its special requirements. High tensile, high temperature resistant, super soft special excitation wire is a new type of material for its special requirements. The special comprehensive cable product with a new structure designed can not only meet the matching requirements of vehicle-mounted and ship-borne electronic equipment, but also meet the supporting requirements of other high-tech equipment electrical equipment and system electronic equipment.

Utility model content

The purpose of the utility model is to provide a high-tensile, high-temperature-resistant, super-soft special excitation wire in order to make up for the defects of the prior art.

The utility model is achieved through the following technical solutions:

A super-flexible special excitation wire, characterized in that it includes a wire core, the wire core is twisted with 180°C grade polyesterimide enamelled round copper wire, the outer diameter of the wire core is not greater than 6.5mm, and the wire core The outer side of the wire core is tightly wrapped with a wrapping layer, and the outer side of the wrapping layer is wrapped with a sheath. The sheath is braided with glass fiber and coated with silicone paint. The outer diameter of the finished wire is not greater than 7.5mm.

The characteristic of the super soft special excitation wire is that the wire core size is 2700/0.085mm.

The characteristic of the super-soft special excitation wire is that the wrapping layer is made of two layers of tightly wrapped polyester filaments.

The utility model has the advantages of:

The utility model has the advantages of high temperature resistance, high tensile strength, light weight, high heat resistance stability, frequent bending without affecting the transmission effect and the like.
