Description
Technical field
The utility model is specifically related to the fire-retardant communication cable of a kind of clad type.
Background technology
Telecommunication cable typically comprises multiple insulated electric conductors wherein.In order to make the minimise issues of interference between electric wire and random noise, electric wire in cable is generally twisting, the high-speed data communications cables of at least one type comprises the cable core wherein with multiple twisted pair, and around the insulation protective case of this cable core, line is to being arranged to the impedance according to wherein high-speed data and communication network in a certain way, decay, distortion and crosstalk make Performance optimization.
More known twisted cables comprise the right independent compartment of each twisting in cable, these compartments by shell structure or the movement being formed to prevent twisting right with the insulating element surrounded by protective case and less twisting between crosstalk, typically, insulating element is made by insulating material and has certain thickness, this thickness is selected as retention wire to being separated from each other, by providing thicker insulating element, online between be provided with larger interval, because this reducing crosstalk, but, thicker insulating element adds the overall diameter of cable, it can increase the cost of cable and complexity and the pliability that can reduce cable makes it more be difficult to install.
Because telecommunication cable is configured to higher speed and frequency transmission, therefore the insulating element insulated is verified will be unsuccessful in crosstalk reduction to tolerable injury level, the known twisted cable of at least some comprises the interlayer as shield member work, these interlayers typically comprise metal insert, these metal inserts are enclosed to, or be inserted in addition in the insulating element of insulation, problem is that these traditional shielding interlayers make and assemble costly, in addition, traditional shielding interlayer keeps relatively thick, because this increasing the volume of cable.
