Abstract
The utility model discloses a silicon rubber insulation instrument cable. Insulated cores are pair-twisted to form line set units by two or three line sets; a wrapping tape layer and an auxiliary shielding layer are arranged outside the line set units which are further intertwisted into cable cores; a filled layer is arranged between the cable cores; a second wrapping tape layer, a main shielding layer, a main wrapping tape layer and an outer sheath layer are sequentially arranged outside the cable cores and the filled layer; each insulated core is composed of a core body, a fire retarding layer and a ceramic silicon rubber insulating layer; and the insulating layer and the outer sheath layer are formed through extruding the ceramic silicon rubber. The cable has the advantages that the environmental protective performances such as low smoke, halogen free and fire prevention are provided and the signal transmission is good and stable.
Description
Technical field
The utility model belongs to the electric wire field, relates to a kind of silicon rubber insulation instrument cable.
Background technology
The signal transmission of present distributing system in industrial and mining enterprises such as electric power, metallurgy, chemical industry, electronic computer system, automated system and detecting instrument, instrument etc. are done connecting line.Basically adopt traditional flame-proof polyethylene flame-resistant insulation pvc sheath and common silicone rubber for cable.Flame-proof polyethylene flame-resistant insulation pvc sheath cable heatproof is 105 ℃, and common silicone rubber for cable is high temperature resistant only to be 180 ℃.When fire occurs, cable is namely burned, has the amount of being fuming height, there are halogen and poisonous corrosive gas to disengage, are unfavorable for like this withdrawing and rescuing of personnel, and because the release of the corrosivity gas such as halogen is arranged, with airborne steam in conjunction with forming strong acid mist, be attached on the electric device, seriously reduce the dielectric strength in equipment and earth connection loop, cause " secondary disaster ".
The utility model content
Use the problem that exists for overcoming existing Common Instrument cable at the dangerous situation that some have fire to occur, the purpose of this utility model is to provide a kind of high temperature resistant fireproof ceramic silicone rubber cable, is a kind ofly will hang down the cable that the environmental-protecting performance such as cigarette, Halogen, fire prevention and good stable signal transfer functions are integrated in one.
Scheme of the present utility model is as follows: a kind of silicon rubber insulation instrument cable, its insulated wire cores forms line group unit by two line groups or three line group pair twists, online group unit is outside equipped with belting layer and sub-shield, line group unit is twisted into cable core again, and packed layer is set between cable core, cable core and packed layer are disposed with the second belting layer, total screen, overall budget belt and outer jacket outward; Described insulated wire cores is comprised of conductor, flame retardant coating and ceramic silicone rubber insulation layer; Described insulating barrier and external sheath layer adopt ceramic silicon rubber to extrude formation.
Described packed layer adopts the low smoke, zero halogen glass fiber rope to fill and forms.
Described the second belting layer adopts the wrapped formation of LSOH anti-flaming glass fibre belt.
The beneficial effects of the utility model:
1, wrapped mica tape on the conductor of cable, insulating layer material adopt enviroment protective ceramic SiClx rubber-covered material, and this material is compared with common polyethylene, and is nontoxic, tasteless at normal temperatures, has good flexibility and elasticity, possesses the feature of silicon rubber; Under flame condition, can very effectively stop burning away of flame; And behind burned 2 ~ 4min, give up smoking fully.
2, the outer jacket of cable adopts environment-friendly ceramic SiClx rubber sheath material.This material has taken into full account the Halogen of cable, low cigarette, fire resistance, adopts novel high polymer ceramic silicon rubber composite material, on every side personnel and equipment without illeffects.
3, the auxiliary packing material of cable and band material are to adopt halogen-free flameproof glass fiber material, not only have good fire resistance, and all are not halogen-containing environment-friendly materials.
Description of drawings
Fig. 1 is structural representation of the present utility model.
