Abstract
The utility model relates to a cable structure, in particular to a refractory ceramics silica rubber cable. The refractory ceramics silica rubber cable comprises a conductor and is characterized in that: the conductor is externally sleeved with a refractory ceramics silica rubber insulation layer; and the refractory ceramics silica rubber insulation layer is externally sleeved with a refractory ceramics silica rubber sheath layer. The refractory ceramics silica rubber cable mainly solves the defects that the existing refractory cable has worse refractory performance, is not easy bent, has complicate process technology, is not convenient due to repeated joint mounting construction, has low insulating resistance, has serious insulating pulverization and can not tolerate impact and beat during combustion; meanwhile, the refractory ceramics silica rubber cable has very simple structure, and the process technology is not complicate.
Description
Technical field
The utility model relates to the construction of cable, particularly a kind of refractory silicone rubber for cable.
Background technology
China fire-resistant wire and cable market mainly is based on inorganic mineral insulation cable, wrapped mica tape plastic insulated cable at present.Though inorganic mineral insulation cable has the superior advantage of fire resistance, it has shortcomings such as not flexible, that processing technology is complicated, need repeatedly joint installation inconvenience, insulation resistance is lower.Wrapped mica tape plastic insulated cable is as the substitute products of inorganic mineral insulation cable, fire resistance is relatively poor though simple its of processing technology has, during burning the insulation efflorescence seriously not withstand shock shortcoming such as beat.
The utility model content
The purpose of this utility model is to provide a kind of refractory silicone rubber for cable, it is relatively poor that it mainly solves existing fire-resisting cable fire resistance, not flexible, processing technology is complicated, need repeatedly joint installation inconvenience, insulation resistance is lower, during burning the insulation efflorescence seriously not withstand shock shortcoming such as beat, and its structure is very simple, and processing technology is uncomplicated.
The utility model solves the problems of the technologies described above the technical scheme that is adopted.
A kind of refractory silicone rubber for cable, it comprises conductor, it is characterized in that: the outer sheathed refractory silicone rubber insulation layer of described conductor, the outer sheathed refractory silicone rubber jacket layer of this refractory silicone rubber insulation layer.
Described refractory silicone rubber for cable is characterized in that: described outside diameter of cable scope is 2.2～10.4mm.
Described refractory silicone rubber for cable is characterized in that: described refractory silicon rubber insulation layer thickness is 1.0～2.2mm.
Described refractory silicone rubber for cable is characterized in that: described refractory silicone rubber jacket layer thickness is 1.0～3.0mm.
The beneficial effects of the utility model are.
1, adopts two layers of refractory insulating layer structure of the present utility model.Refractory silicon rubber temperature resistant grade can reach 1300 ℃.Rated voltage 1000V.
2, the utility model insulating barrier process using is the formula of extruding, and insulation thickness and product external diameter are controlled easily, external diameter scope 2.2～10.4mm.Than the hot-face insulation outside diameter of cable decreased average of relevant voltage grade 1/3rd.
3, the utility model structure is very simple, and processing technology is uncomplicated.
4, advantages such as the soft bending property of the utility model cable, insulation resistance height, installation convenience are the optimal selections that substitutes inorganic mineral insulation cable.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
See also Fig. 1, the utility model discloses a kind of refractory silicone rubber for cable.As shown in the figure: it comprises conductor 1, described conductor 1 outer sheathed refractory silicone rubber insulation layer 2, these refractory silicone rubber insulation layer 2 outer sheathed refractory silicone rubber jacket layers 3.Described outside diameter of cable scope is 2.2～10.4mm.Described refractory silicone rubber insulation layer 2 thickness are 1.0～2.2mm.Described refractory silicone rubber jacket layer 3 thickness are 1.0～3.0mm.
Potteryization silicon rubber fire-resisting cable of the present utility model has extraordinary fire prevention, fire-resistant, fire-retardant, low cigarette, nontoxic performance, the cable of making of this potteryization silicon rubber, form ceramic duricrust and not fusion under the environment of fire (600～1300 ℃) at its insulating barrier sintering after the burning, do not drip, can anti-beaten by certain impact, thereby ensure cable circuit unimpeded under fire condition, and the potteryization silicon rubber insulated cable has the soft bending property of good cable, the insulation resistance height, processing technology is simple, advantages such as installation is convenient are the optimal selections that substitutes inorganic mineral insulation cable.
In sum, be preferred embodiment of the present utility model only, be not to be used for limiting practical range of the present utility model, promptly all equivalences of doing according to the content of the utility model claim change and modify, and all should be technology category of the present utility model.
