Description

Fire-resistant wire

Technical field

The utility model is related to electrician's Power-line technology field, more particularly to a kind of fire-resistant wire.

Background technology

The external insulation of flame retardant silica gel electric wire is mostly individual layer flame retardant silica gel structure at present, and mechanical property is poor, tension Intensity is low, easy fracture, proof voltage poor performance, the service life of electric wire and the stability of circuit is greatly influenced, in order to improve electricity The synthesis performance of line is, it is necessary to the design more innovated to wire structure.

Utility model content

For above-mentioned technical problem, the utility model provides a kind of fire-resistant wire, has unique structure design, resistance Fuel efficiency fruit is good, mechanical performance is high, excellent electrical properties, highly practical.

To realize that above-mentioned skill states purpose, the utility model employs following technical solution：

A kind of fire-resistant wire, it is characterised in that：Including cored wire and the insulating layer being arranged at outside cored wire, the insulating layer bag Include interior layer of silica gel and outer layer of silica gel, the thickness ratio of interior layer of silica gel and outer layer of silica gel is (1.5 ~ 2):1, outer layer of silica gel is using fire-retardant Silica gel is made.

Preferably, the cored wire is formed using two strands or more of copper wire twisting, the coat of metal is set on the surface of cored wire.

By adopting the above-described technical solution, the utility model has the following technical effect that：The utility model has uniqueness Structure design, good flame retardation effect, mechanical performance are high, excellent electrical properties, highly practical, suitable for promoting and applying.

Description of the drawings

The utility model will illustrate by example and with reference to the appended drawing, wherein：

Fig. 1 is the structure diagram of the utility model.

Specific embodiment

All features or disclosed all methods disclosed in this specification or in the process the step of, except mutually exclusive Feature and/or step beyond, can combine in any way.

Any feature disclosed in this specification, unless specifically stated, can be equivalent by other or with similar purpose Alternative features are replaced.I.e., unless specifically stated, each feature is an example in a series of equivalent or similar characteristics .

A kind of fire-resistant wire as shown in Figure 1, including cored wire 10 and the insulating layer being arranged at outside cored wire 10, cored wire 10 is used In conduction electric energy, insulating layer includes interior layer of silica gel 1 and outer layer of silica gel 2, the thickness ratio of interior layer of silica gel 1 and outer layer of silica gel 2 for (1.5 ~ 2) :1, internal layer thick outer is thin, and outer layer of silica gel 2 is made of flame retardant silica gel, compared to the insulating layer of traditional single layer structure, greatly Ground improves anti-flammability, and common silica gel can be used in interior layer of silica gel 1.Fully combine the anti-flammability of flame retardant silica gel brilliance and common The advantages that excellent ageing-resistant, proof voltage energy of silica gel and higher mechanical performance.In the present embodiment, cored wire 10 uses two strands Above copper wire twisting forms, and the coat of metal is preferably provided on the surface of cored wire 10, further improves the tensile strength of electric wire, no Easy fracture, excellent in mechanical performance.

The utility model is not limited to foregoing specific embodiment.The utility model expands to any in this specification The step of new feature of middle disclosure or any new combination and any new method or process disclosed or any new group It closes.
