Abstract
The utility model discloses a silicon rubber insulated braided heat-resisting flexible wire which comprises a conductor, wherein the conductor is formed by twisting an inner layer and re-twisting an outer lay with 15-135 single tinned copper wires with the diameters of 0.12-0.45 mm, a silicon rubber insulated layer is formed outside the conductor by extrusion molding, a fire-resisting layer and a fiber glass protection layer are arranged outside the silicon rubber insulated layer sequentially, and the fiber glass protection layer is integrally formed by sheath materials of a sheath layer and a netty braided layer braided by a fiber glass filaments through extrusion molding. The flexible wire is reasonable in structural design, with the adoption of the fire-resisting layer and the fiber glass protection layer, both the fire resistance and the tear resistance of a cable are improved effectively, the stability of information transmission is ensured, and the service life of the cable is prolonged.
Description
Technical field:
The utility model relates to electric wire, relates in particular to a kind of silicon rubber insulation and weaves heat-resisting flexible cord.
Background technology:
Wires and cables industry is the second largest industry that China is only second to automobile industry, and product variety satisfies rate and domestic market occupation rate all above 90%.Worldwide, the Chinese electric wire gross output value has surpassed the U.S., becomes in the world first electric wire producing country.Be accompanied by Chinese wires and cables industry high speed development, creation of new enterprise quantity constantly rises, and industry overall technology level is largely increased.
Ac rated voltage 500V and following silicone rubber for cable, mainly be to use for fixedly laying with power transmission line or movable electrical appliances connecting line, silicon rubber generally has the characteristics such as good heat-resisting radiation, cold-resistant, acid and alkali-resistance and corrosive gas, waterproof, the construction of cable is soft, radiation is convenient, and electric property is stable under high temperature (high and cold) environment, and ageing resistace is outstanding, long service life is widely used in the industries such as metallurgy, electric power, petrochemical industry, electronics, automobile making.
Original silicon rubber heat-resisting flexible cord causes cable transmission of information stability to can not get ensureing because fire resistance and tear resistance do not reach the demand of actual working environment.
The utility model content:
In order to remedy the defective of prior art, the purpose of this utility model provides a kind of silicon rubber insulation and weaves heat-resisting flexible cord, reasonable in design, and fire resistance, tear resistance are superior.
The technical solution of the utility model is as follows:
Silicon rubber insulation weaves heat-resisting flexible cord, comprise conductor, it is characterized in that: it is to twist again skin behind 0.12～0.45mm tinned copper wire single line bundle strand internal layer to consist of that described conductor adopts 15～135 diameters again, the outer extrusion moulding of conductor has silicone rubber insulation layer, silicone rubber insulation layer is provided with flame retardant coating, glass fibre sheath outward successively, and the glass fibre sheath is that the protective cover material of restrictive coating is netted braid formation one through extrusion molding and glass fiber braiding.
Described silicon rubber insulation weaves heat-resisting flexible cord, it is characterized in that: the protective cover material of described restrictive coating adopts tear-proof silicon rubber.
The utility model has the advantages that:
The utility model reasonable in design by flame retardant coating and glass fibre sheath, improved fire resistance and the tear resistance of cable effectively, ensured the stability that information is transmitted, and prolonged cable useful life.
Description of drawings:
Fig. 1 is structural representation of the present utility model.
