Description
Technical field
The utility model relates to field of cable technology more particularly to a kind of inorganic ceramic fireproof cables.
Background technique
The application places of cable are relatively complicated, these complicated places propose challenge to the safe operation of cable.
It is to influence mostly important one of the factor of cable running safety that fire, which is suffered from, how to guarantee the normal operation of cable under the high temperature conditions,
It is the cable manufacturing enterprise technical issues that need to address.In recent years, Minstry of Housing and Urban-Rural Development of People Republic of China (MOHURD), the Ministry of Public Security and some local governments went out in succession
The some electrical design specifications of platform, require the security level of electric wiring higher and higher, and clear stipulaties are some important
Electric wiring and place must use fireproof cable.
Utility model content
The utility model aim is exactly in order to make up the defect of prior art, to provide a kind of inorganic ceramicization anti-thermoelectricity
Cable.
The utility model is achieved through the following technical solutions:
A kind of inorganic ceramic fireproof cable, includes cable core, and the cable core includes that there are four rubber skeletons, described
Rubber skeleton include there are two fan-shaped skeleton and a semicircle skeleton, one end of two fan-shaped skeletons is connected, two sectors
The other end of skeleton is separately connected the both ends of semicircle skeleton, and the radius of fan-shaped skeleton is equal to the radius of semicircle skeleton, fan
The arc-shaped side of shape skeleton is quadrant arc, four rubber skeletons is placed in quadrangle and outside four semicircle skeleton phases
It cuts, is provided with the first core on the inside of each semicircle skeleton, be provided with the second core, In in each fan-shaped skeletal internal
It is provided with third core in the gap formed between four rubber skeletons, is successively coated with Ceramic silicon rubber in the outside of cable core
Sheath, ceramic fiber cloth wrapping layer, plastic-aluminum combined membrane shield layer and double-tape armor polyvinyl chloride oversheath；Described
Low-smoke halogen-free polyolefin insulating layer and the copper modeling that one core includes the first conductor and is successively coated on the outside of the first conductor are multiple
Crossed belt wrapping layer, the polyimides that second core includes the second conductor and is successively coated on the outside of the second conductor are exhausted
Edge layer, fiber band wrapping layer and the Tarpauling wrapping layer for being coated with semiconductive colloid, the third core includes that third is led
Body and the polypropylene insulation layer being coated on the outside of third conductor.
Between the semicircle skeleton of described four and it is respectively adopted adhesive between third core and is adhesively fixed.
First conductor, the second conductor and the third conductor is as made of silver-gilt copper wire bundle strand.
The utility model has the advantages that: rubber skeleton of the invention is to add a semicircle skeleton using two fan-shaped skeletons
The skeleton of the irregular shape of composition, structure is relatively new, and core is all put into skeletal internal, energy when cable is squeezed bending
Protection core well, four rubber skeletons are oppositely arranged, and energy 360 degrees omnidirection resistance to compression successively coats in the outside of cable core
There are Ceramic silicon rubber sheath, ceramic fiber cloth wrapping layer, plastic-aluminum combined membrane shield layer and double-tape armor polyvinyl chloride
There is the sheath of protection effect ensure that fireproofing of cable performance well for oversheath, multilayer, and structure is simple, small in size, resistance to compression
It is antitorque wear-resisting, long service life.
