Abstract
A metal braided shielding armoured control cable comprises a metal conductor wrapped with an insulating layer, wherein the outer side of the insulating layer is wrapped with a metal braided shielding armoured layer, a sheath is arranged outside the metal braided shielding armoured layer, and a polyester film lining layer is arranged between the insulating layer and the metal braided shielding armoured layer. Compared with the prior art, the control cable has the advantages that firstly, the polyester film lining layer for electric insulation is only 0.023-0.050 mm in thickness, has tensile strength larger than 150 MPa, over 60% elongation at break and 130 kV/mm dielectric strength, guarantees the performance, and reduces the outer diameter of the cable, secondly, the shielding armoured layer braided by metal wires can prevent hydrostatic interference and electromagnetic induction, effectively protects a cable core from being damaged by machines, and reduces the minimum bending radius during the installation of the cable, and thirdly, the lining material and steel belts or steel wires are omitted, which enables the control cable to have light weight, material conservation and convenient transportation and installation.
Description
Technical field
The utility model relates to optical-fibre communications field, particularly a kind of metal knitted shield control cable.
Background technology
In the existing structure of the control cable with sheathed structure, what all have avoids the inner covering that armour injures in order to the protection cable core.The thickness of inner covering is 1.0～1.2mm.This structure is concerning steel band and steel wire armoured cable, reasonably necessary beyond doubt, but the metal base transistor cable just is worth weighing: metal knitted employing diameter only is annealing copper wire or the tin plated steel wire of 0.2～0.4mm, the injury that they may cause cable core is much smaller than steel band and wire armoring, if also adopt identical sheath structure, obviously not too reasonable: both waste material, increase cost, make that again cable weight is big, install, all inconvenience of transportation.
The utility model content
Technical problem to be solved in the utility model is at above-mentioned prior art present situation, and to provide a kind of both economical with materials, convenient again transportation, the metal knitted shield control cable of installing.
The utility model solves the problems of the technologies described above the technical scheme that is adopted: metal knitted shield control cable, comprise the plain conductor that is wrapped with insulating barrier, described insulating barrier is wrapped with a metal knitted shield layer, outside described metal knitted shield layer, a sheath is set, it is characterized in that: between described insulating barrier and metal knitted shield layer, be provided with the polyester film inner covering;
Described plain conductor is a copper conductor; Described metal knitted shield layer is annealing copper wire or the tinned copper wire establishment of 0.2～0.4mm by diameter; The thickness of polyester film inner covering is 0.023～0.050mm.
Compared with prior art, advantage of the present utility model is, (1) polyester film that is used for electric insulation only is 0.023～0.050mm as inner covering thickness, but its hot strength is greater than 150MPa, elongation at break is greater than 60%, dielectric strength 130kV/mm has guaranteed performance, has reduced the outside diameter of cable; (2) the shield layer that adopts the tinsel braiding to constitute had both prevented electrostatic interference and electromagnetic induction, had also protected cable core to avoid mechanical damage (can bear certain pulling force and pressure) effectively, had reduced the minimum bending radius when cable is installed simultaneously; (3) omitted inner lining material and steel band or wire material, made that the utility model is in light weight, the joint material, convenient transportation, installation.
Description of drawings
Fig. 1 is the cross section structure schematic diagram of the utility model embodiment.
Embodiment
According to embodiment and accompanying drawing the utility model is described in further detail below.
As shown in Figure 1, a kind of metal base transistor control cable comprises copper conductor 1, and described copper conductor 1 outer continuous, even, tight extruded insulation layer 2 is formed insulated wire cores; Two such cores or the insulated wire cores more than two cores are twisted into cable core, the thick polyester film inner covering 3 of two layers of 0.05mm of overlapping wrapped or vertical bag outside cable core, the minimum overlay rate is not less than 15%, adopt the shield layer 4 of circular copper wire braiding formation again on outer, it only is annealing copper wire or the tinned copper wire of 0.2～0.4mm that its braiding circular copper wire adopts diameter.Outside the shield layer 4 of circular copper wire or zinc-plated circular copper wire braiding formation, one deck sheath 5 is set.
