Description

Cable

Technical field

This utility model is related to field of electrical equipment, more particularly, to cable.

Background technology

Polyether-ether-ketone, English name polyetheretherketone (abbreviation PEEK), it is to contain chain in molecular backbone The linear aromatic race macromolecular compound of section.Its component unit be oxygen-to phenylene-oxygen-carbonyl-to phenylene, be hemicrystalline, Thermoplastic.

Name of product：Polyether-ether-ketone (PEEK) resin is a kind of special engineering plastics of excellent performance, with other extraordinary works Engineering plastics are compared has more significant advantages, and 260 degree of resistance to positive high temperature, mechanical performance is excellent, self lubricity is good, chemicals-resistant is rotten Erosion, fire-retardant, peel resistance, wearability, can be used for high-end machine intolerant to strong nitric acid, concentrated sulphuric acid, radioprotective, superpower mechanical performance The science and technology such as tool, nuclear engineering and aviation.

Polyimide fiber, elastic modelling quantity is only second to carbon fiber, as the filtering material of high-temperature medium and radioactive substance With shellproof, fire-proof fabric.

Polyarylate is a kind of heat-resist, wider using temperature, can at -70-+180 DEG C life-time service, anti-flammability is good Engineering thermoplastic mould.

Liquid crystal polymer fibre because its to have high intensity, high rigidity, high temperature resistant, electrical insulating property etc. very excellent, by with In fields such as electronics, electric, optical fiberss, automobile and aerospace.The fiber being made with liquid crystal can do fishing net, ballistic protective clothing, physical culture A few display material of articles for use, brake block, optical fiberss etc., may also be fabricated which thin film, for soft printed wire, packaging for foodstuff etc..Heat Cause liquid crystal polymer also can make polymer blending material with multiple plastics, in these intermingling materials, liquid crystal polymer plays fiber Enhanced effect, can greatly improve intensity, rigidity and thermostability of material etc..

At present, with scientific and technical development, also in rapid advances, bring therewith is cable consumption in the field such as industry Increase, cable typically has the cable of several or every group of at least two stranded similar ropes of several groups of wires, every group of wire Between mutually insulated, and be often twisted into around a center, whole outside is surrounded by the cover layer of high-insulation, the species of cable has very Many, can apply that the use environment in different fields is different in a lot of fields, therefore cable also be had not Same requirement, existing cable is unreasonable because of its structure design, can not meet needs, and general cable in high temperature or occurs fire It is easy to the situation of burning during calamity, it can discharge the gas that environment and human body are harmful to, Er Qie electricity in combustion The damage of cable epidermis, can cause electrical fire, bring bigger loss.

In social life, fire is to threaten public safety, one of disaster of harm people's lives and properties.Now, fire It is the common wicked problems that the people of other countries are faced.It caused many life, property to human society Heavy losses.With the development of social productive forces, the wealth of society increasingly increases, and fire damage rises and fire hazard expanded range General trend be objective law.However, conventional power cable heatproof is low, fire protecting performance is poor, brings very to fire prevention rescue works How inconvenient.

Utility model content

The technical solution of the utility model is：Cable, including central conductor and carbon nanotube layer it is characterised in that：Described The outer wrap carbon nanotube layer of central conductor, the outside of carbon nanotube layer is lapping layer, and the periphery of lapping layer is compositional flame-retardant Layer, the periphery of compositional flame-retardant layer is oversheath, and oversheath is that (linea low density gathers POE (polyethylene octene copolymer) and LLDPE Ethylene) binary blend resin, oversheath contains aluminium hydroxide fire retardant, and compositional flame-retardant layer is aluminium hydroxide and Firebrake ZB, Lapping layer is combined twining package tape by Ceramic silicon rubber and makes.
