Description
Technical field
The utility model relates to cable technology field, relates in particular to a kind of heat insulation cable.
Background technology
At present, all need to use cable, and high temperature brings infringement can to long-time cable in hot environment, easily makes cable accelerated ageing in a lot of high temperature place, existing cable cannot well completely cut off the impact that outside hot environment is brought to cable.
Utility model content
The utility model object is exactly the defect in order to make up prior art, and a kind of heat insulation cable is provided.
The utility model is achieved through the following technical solutions:
A kind of heat insulation cable, include core etc., described core includes center-point earth core and four strands of power cores around, insulating barrier and screen that described center-point earth core is provided with successively by earth connection core conductor and outside thereof form, the insulating barrier that described power core is provided with successively by four power line core conductors and conductor outside, screen composition, per share power core is made up of four power cores and is coated with lapping layer in its outside, four strands of power cores are separated by the silicon rubber skeleton of four jiaos of stars and are placed on respectively between two jiaos of skeleton, skeleton middle part is provided with through hole, the built-in center-point earth core of through hole, four bursts of power core outsides are also provided with braid successively, armour, fireprotection layer and sheath.
The utility model has the advantages that: the utlity model has good heat-proof quality, cable can be moved for a long time under the condition of high temperature, extend cable useful life, cost-saving.
