Abstract
The utility model discloses a self-supporting communication cable. The self-supporting communication cable comprises multi-strand insulated signal cables, wherein an insulating protective layer is coated outside the multi-strand insulated signal cables. The self-supporting communication cable is characterized in that the self-supporting communication cable further comprises steel cores of which the outside is coated by an insulating protective layer, the multi-strand insulated signal cables coated with the insulating protective layer and the steel cores coated with the insulating protective layer form a self-supporting communication cable core, and a shielding layer and an outer insulating protective layer are sequentially coated outside the self-supporting communication cable core. The self-supporting communication cable is reasonable in design, simple in structure and good in insulating effect; and as the steel cores and an aramid rope insulating filler are additionally arranged, the gravity of the cable can be undertaken, support and ancillary materials are not required during erection, and the self-supporting communication cable has signal transmission and anti-interference capabilities. The self-supporting communication cable solves the technical problems of high erection cost and low work efficiency in the prior art.
Description
Technical field the utility model belongs to the communication apparatus technical field, relates to a kind of cable, particularly relates to a kind of from the multiplier communication cable.
Background technology is present; The non-self-bearing type communication cable of extensive use can not directly set up, and need it be hung on the supporting object such as steel wire, sleeve pipe of prior construction with special gold utensil, and it is lower to set up efficient; Need attaching materials such as extra increase steel wire, gold utensil, increased and set up cost.
The purpose of summary of the invention the utility model is to solve the prior art existence to set up cost height, ineffective technical problem, provides a kind of from the multiplier communication cable, to overcome the deficiency of prior art.
The utility model comprises multiply insulation RCA from the multiplier communication cable, and the outside of multiply insulation RCA is coated with insulating protective layer; Its main points are that it comprises that also the outside is coated with the steel core of insulating protective layer; The said multiply insulation RCA that is coated with insulating protective layer constitutes from multiplier communication cable core with the steel core that is coated with insulating protective layer, said screen and the external insulation protective layer of outside multiplier communication cable core, being coated with successively.
In order further to improve weight capacity, saidly set up aramid fiber rope insulation filler from multiplier communication cable in-core from the multiplier communication cable.
The utility model is reasonable in design, and is simple in structure, and insulation effect is good, can bear cable gravity owing to set up steel core, aramid fiber rope insulation filler, need not support and attaching material when setting up, and possess signal transmission and antijamming capability.The utility model has solved the prior art existence and has set up cost height, ineffective technical problem.
Appended drawings is the utility model radial section structural representation.
The embodiment accompanying drawing has provided a specific embodiment of the utility model; Below in conjunction with accompanying drawing the utility model is elaborated: shown in accompanying drawing; The utility model is from the multiplier communication cable; Comprise multiply insulation RCA 4, the outside of multiply insulation RCA 4 is coated with insulating protective layer 3; It comprises that also the outside is coated with the steel core 6 of insulating protective layer 5; The multiply insulation RCA 4 that is coated with insulating protective layer 3 constitutes from multiplier communication cable core 8 with the steel core that is coated with insulating protective layer 56, is coated with screen 2 and external insulation protective layer 1 successively from multiplier communication cable core 8 outsides; In order further to improve weight capacity, in multiplier communication cable core 8, set up aramid fiber 7 insulation filler of restricting from the multiplier communication cable.
External insulation protective layer 1 is anti-aging material, can set up in the open, need not use sleeve pipe, set up time saving and energy saving, to set up cost low; Internal shield 2 is made up of wire netting, can effectively prevent electromagnetic interference; Steel core 6 is made up of steel wire strand, can bear cable gravity; Aramid fiber rope 7 is a kind of high-performance staple fibres, and tensile strength is high, heat resistance is strong, can strengthen the cable bearing capacity.
