Abstract

The utility model discloses a fusiform control cable. The fusiform control cable comprises three conductors. The outside of each conductor is coated with an inorganic insulating layer, the three conductors coated with the inorganic insulating layers are distributed like a Chinese character 'pin' in each region of a Y-shaped framework to form a cable core, the Y-shaped framework is made from polyethylene or a thermoplastic elastomer through the extrusion moulding process, the outside of the cable core is coated with a wrapping layer which is formed by wrapping the superposed double-layer polyester thin film strips around the outside of the cable core in an overlapping manner, a filling layer which is made from high temperature resistant glass fibers is arranged between the wrapping layer and the cable core, a fusiform sheath layer is formed on the outside of the wrapping layer through the extrusion moulding process, and two ends of the sheath layer are provided with tensile strips formed by braiding small-gauge wires respectively. According to the utility model, the cable core is supported by the framework, and the tensile ropes are arranged on the sheath layer, so the mechanical performance of the cable is improved; the refractory performance and the fireproof performance of the cable are improved through the design of the wrapping layer and the filling layer; and the insulating layers and the sheath layer are made from mixing silicone rubber, so advantages of good electrical performance and good flexibility can be realized on the cable in the high temperature condition, the low temperature condition and the corrosive condition.

Description

A kind of fusiformis control cables

Technical field:

The utility model relates to control cables, relates in particular to a kind of fusiformis control cables.

Background technology:

Silicon rubber control cable: mainly be applicable to ac rated voltage 450/750V and following movement or fixedly lay the electrical appliance instrument leads or the signal transmission, cable has preferably thermal stability, can in high temperature, low temperature, corrosivity, keep good electrical property and flexibility, be fit to the industries such as metallurgy, electric power, petrochemical industry and have the specific (special) requirements occasion uses such as mobile heatproof.

The mechanical performance of original silicon rubber control cable is relative with the fire resistant performance relatively poor, and the actual application performance can't satisfy the demands.

The utility model content:

For the prior art problem, the purpose of this utility model provides a kind of fusiformis control cables, and the structural design advantages of simple has improved mechanical performance and the fire resistant performance of cable effectively, has prolonged the useful life of cable.

The technical solution of the utility model is as follows:

The fusiformis control cables, it is characterized in that: comprise three conductors, described three conductors are enclosed with respectively inorganic insulation layer outward, three conductors of parcel inorganic insulation layer are distributed in a triangle Y shape skeleton regional and consist of cable core, the Y shape skeleton adopts polyethylene or thermoplastic elastomer (TPE) extrusion moulding, cable core is wrapped with the lapping layer of the rear overlapping wrapped formation of double-layer polyester film strip stack, be provided with the packed layer that the pyroceram silk consists of between lapping layer and the cable core, the outer extrusion moulding of lapping layer has the restrictive coating of fusiformis, and the two ends of restrictive coating are provided with the tension band that finer wire is woven into.

Described fusiformis control cables is characterized in that: it is melting silicone rubber that described inorganic insulation layer and restrictive coating adopt material.

The utility model has the advantages that:

The utility model cable core adopts the tension rope that skeleton supports, restrictive coating is interior, improved the mechanical performance of cable, the design of lapping layer and packed layer has improved the fire-resistant fire protecting performance of cable, insulating barrier and restrictive coating adopt melting silicone rubber, so that cable can keep good electrical property and flexibility in high temperature, low temperature, corrosivity.
