Abstract
The invention relates to a novel self-control heating cable structure. The novel self-control heating cable structure is provided with a main insulation layer, the cross section of the main insulation layer is of an elliptical-shaped structure, the main insulation layer is internally provided with three cable cores, the cable cores are arranged in a linear mode, each cable core is internally provided with a bus insulation layer and a bus, the bus of each cable core is wrapped by the corresponding bus insulation layer of the cable core, each bus is a copper wire or an aluminum wire, the main insulation layer is externally wrapped by a heating filament layer, the heating filament layer is internally provided with a heating filament, the heating filament layer is externally wrapped by an oversheath layer, the oversheath layer is externally wrapped by an insulation braided layer, and the insulation braided layer is externally wrapped by a reinforced sheath. The novel self-control heating cable structure is reasonable in structure and advanced in manufacturing process and technical flow, can meet stipulations and requirements of correlation standards, and meets user demands. A material with small thermal resistance and good electrical and mechanical performance is selected for insulation, the normal-state insulation resistance is equal to and greater than 50 megaohm.Km, a metal wire braided shielding layer is employed, and the best shielding effect can be achieved.
Description
Technical field
The invention belongs to cable preparation field, be specifically related to a kind of novel automatic control heating construction of cable.
Background technology
The exploitation application of the Special Wires and Cables with environmental protection, the advantage such as energy-conservation has become as one of China's wires and cables industry main development direction the Eleventh Five-Year Plan period.Meanwhile, on national policy leads, clearly proposing to give priority to " environmental protection, energy-conservation " product, after particularly listing non-renewable resources in national strategy resource, Renewable resource such as wind-powered electricity generation, water power, nuclear power will be developed further.Under this background, showing one's talent of special cable, nature can attract increasing enterprises pay attention.Add the heating utensil that electric heating cable is a kind of specific form, the heating plant of the best is manufactured in combinations with the special requirement of each side such as industry, agricultural and building industry, along with completing that China's urban and rural power grids are tentatively transformed, and the increasing substantially of electricity supply, electrical heating is used to have the more advantages such as cleaning, environmental protection, the development and application adding electric heating cable is all had certain facilitation by these, and the quality of current this cable is ripe not enough.
Summary of the invention
The present invention overcomes the deficiencies in the prior art, it is proposed that a kind of novel automatic control heating construction of cable, and the described construction of cable is reasonable, and manufacturing process and technological process are advanced, can meet correlation standard requirement, meet user's request.The present invention select a kind of thermal resistance little, electrically and the material of good mechanical performance to serve as insulation, normality insulation resistance >=50M Ω Km, dielectric strength: 2500V, 50HZ/min, adopt metal wire knitted screen layer, easy to use lay occasion what have a bigger pulling force, can be simultaneously reached best shield effectiveness.
The technical scheme is that
A kind of novel automatic control heating construction of cable, it is provided with main insulating layer, the ellipsoidal cross section structure of described main insulating layer, three cable cores it are provided with in the inside of main insulating layer, described cable core is inline, bus insulation layer and bus it is provided with in cable core, described bus is wrapped up by described bus insulation layer, bus is copper cash or aluminum line, outer wrap at main insulating layer a heating wire layer, it is provided with heating wire in heating wire layer, outer wrap at heating wire layer external sheath layer, outer wrap at external sheath layer insulation braid, the outer wrap of described insulation braid reinforced sheath.
The invention has the beneficial effects as follows:
Present configuration is reasonable, and manufacturing process and technological process are advanced, can meet correlation standard requirement, meet user's request.The present invention select a kind of thermal resistance little, electrically and the material of good mechanical performance to serve as insulation, normality insulation resistance >=50M Ω Km, dielectric strength: 2500V, 50HZ/min, adopt metal wire knitted screen layer, easy to use lay occasion what have a bigger pulling force, can be simultaneously reached best shield effectiveness, the most high-temperature resistant of heating wire layer: 205 DEG C.
