Abstract
The utility model discloses a plastic insulating fireproof control cable which comprises main power core, a monitoring core, a data transmission core, a steel-band armoring layer and a teflon oversheath, wherein the main power core, monitoring core and data transmission core are uniformly arranged outside a stainless steel liner, a fireproof fiber rope braided layer is extruded outside the main power core, monitoring core and data transmission core to form a cable core, gaps in the cable core are provided with a silicone rubber insulating filling layer, and the cable core is successively wrapped in the steel-band armoring layer and the teflon oversheath from inside to outside. The plastic insulating fireproof control cable is prepared according to special requirements of users, the applicability and reliability are fully considered, rapid, safe and stable information/energy transmission between equipment can be reached, and the cable is simple in production, high in structural intensity, high in stability and stable in current.
Description
technical field
The utility model relates to cable, relates in particular to a kind of plastic insulating fireproof control cable.
Background technology
It is larger that fire-resistant control flexible cable is mainly applicable to various fire hazards, the electrical equipment that security against fire importance is higher
And control system, traditional fireproof control cable manufacture craft mainly adopts the wrapped mica tape of conductor as flame retardant coating, thereby play fire-resistant effect, but because mica is more crisp, wrapped or proceed to lower during to operation, may there is the phenomenon that mica comes off, if mica comes off seriously, undoubtedly in use, its fire resistance can be had a greatly reduced quality, fail safe can not be protected, and the general core number of control cables is all more, all needs wrapped on every conductor, produce trouble, structural strength is not high, and stability is bad, and electric current is unstable.
Utility model content
For overcoming above-mentioned deficiency, the utility model object is to provide a kind of plastic insulating fireproof control cable.
Scheme of the present utility model is as follows: a kind of plastic insulating fireproof control cable, comprise active force core, monitoring core, data conveying core, steel-tape armouring layer and polytetrafluoroethylene oversheath, described active force core, monitoring core and data carry core to be evenly arranged on outside stainless steel bushing pipe; It is cable core that described refractory fibre rope braid extrudes active force core, monitoring core and data conveying core; In gap in described cable core, be provided with silicon rubber insulation packed layer; Described steel-tape armouring layer and polytetrafluoroethylene oversheath cover on cable core successively from outside to inside.
Described active force core is by polyethylene layer, to extrude four aluminium alloy conductors to form.
Described monitoring core is by polyethylene layer, to extrude three strands of silver-plated copper core stranded conductors to form.
It is by ceramic silicone rubber insulation layer level, to extrude two strands of silver-plated copper core stranded conductors to form that described data are carried core, and two strands of silver-plated copper core stranded conductors are respectively provided with a drainage core up and down.
The beneficial effects of the utility model: this product is to formulate according to user's specific (special) requirements, take into full account its applicability and reliability, instructions for use between support equipment under the particular surroundings such as the high speed of information and energy, safety, stable transfer, and cable is produced simple, structural strength is high, good stability, current stabilization.
