Description
Technical field
The utility model relates to field of cables, specifically a kind of high temperature-resistant cable.
Background technique
Insulation ag(e)ing and incipient scorch scene easily occur at high temperature for common wiring cable, so that the correlated performance of cable is damaged
And cannot use, high temperature electric wire cable at high temperature can normally firmly task, signal or electric energy transmission performance are unaffected,
It can also ensure that cable has longer service life, but existing high temperature-resistant cable reaches fire-retardant effect using metal mostly
Fruit, but the fusing point of metal is lower than ceramics, therefore should improve to some extent.
Summary of the invention
To solve the above-mentioned problems, the utility model proposes a kind of high temperature-resistant cables.
A kind of high temperature-resistant cable, including cable core, the cable core are aluminium alloy conductor, the aluminium alloy conductor
Outside is extruded with crosslinked polyetylene insulated layer, and the aluminium alloy conductor and crosslinked polyetylene insulated layer are a cable group, institute
The cable group stated is provided with three groups, and isolation stretching group, the isolation stretching group packet are provided between three groups of cable groups
Include the tensile core being located at three groups of cable center, the rubber parts being arranged in outside tensile core, the outside that rubber parts is set and packet
The isolating frame of three groups of cable groups is wrapped, the isolating frame is surrounded with mica twining package tape, the outside of the mica twining package tape
It is provided with metal screen layer, the outside of the metal screen layer is extruded with silicon rubber oversheath.
The cross section of the rubber parts is Y type, and the periphery of the rubber parts is closely pasted with the periphery of cable group
It closes.
The material of the isolating frame is the soft ceramics that can be hardened at high temperature.
It is provided between the aluminium alloy conductor and crosslinked polyetylene insulated layer, between isolating frame and mica twining package tape
For filling and filled layer resistant to high temperature, the filled layer is that asbestos particles mix composition with glass fiber.
The line of centres of three groups of cable groups is equilateral triangle.
The beneficial effects of the utility model are: wrapping cable using the isolating frame of soft ceramic making inside the utility model
Group preserves from so that can harden protection inside cable core under high-temperature condition, races against time for people's rescue；It is wrapped using mica
Band, filled layer and isolating frame cooperate, and improve the high temperature resistance of cable；Tensile core is set at cable center, is improving cable
While compactness, the tensile property of cable is improved.
Detailed description of the invention
The present invention will be further described with reference to the accompanying drawings and examples.
