Abstract
A water-proof impermeable railway signal cable relates to the technical field of cable structures, which comprises a cable core and the cable core comprises four strands of wire cores hinged with one another and petroleum jelly filling material; each strand of wire core comprises a tinned copper wire stranded conductor and a foam polyolefine insulating layer arranged outside the tinned copper wire stranded conductor; and a waterstop taped covering, an aluminum-plastic composite tape moisture-proof shielding layer, a polyvinyl chloride bonded protecting layer, a longitudinal wrap corrugated steel-tape armor layer and a polyvinyl chloride outer sheath are sequentially arranged on the periphery of the wire core from inside to outside. According to the design provided by the utility model, the waterstop taped covering and the aluminum-plastic composite tape moisture-proof shielding layer are adopted, so that the railway signal cable provided by the utility model has the advantage that the resistance to moisture, water and electromagnetic interference is favorable, and can be used in rainy or damp areas.
Description
Technical field
The utility model relates to the technical field of structures of cable.
Background technology
Along with the extension and the technology upgrading of railway, for the performance requirement of its supporting signal cable is higher, particularly the moistureproof anti-tampering outstanding of some rainy humid area cables shows important.
Summary of the invention
The utility model is to have protection against the tide in order to overcome the deficiencies in the prior art, to provide a kind of, block water and the antiseepage sections road signal cable that blocks water that anti-electromagnetic interference performance is good.
The purpose of this utility model is achieved in that the antiseepage sections road signal cable that blocks water, comprise cable core, cable core comprises mutually stranded four cores and petroleum jelly inserts, and every core is respectively by the tinned copper wire stranded conductor be arranged on the outer foam polyolefin insulating barrier of tinned copper wire stranded conductor and constitute; The periphery of described cable core sets gradually the waterstop lapping layer from inside to outside, aluminium-plastic tape keeps off damp screen, polyvinyl chloride bonding sheath, vertical bag wrinkle steel-tape armouring layer and polyvinyl chloride oversheath.
The utility model is by above design, owing to adopted waterstop lapping layer and aluminium-plastic tape to keep off damp screen, makes cable have protection against the tide, block water and advantage such as anti-electromagnetic interference performance is good, can use in rainy humid area.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
As shown in Figure 1, be the antiseepage sections road signal cable that blocks water, comprise cable core 1, cable core 1 comprises mutually stranded four core 1-1 and petroleum jelly inserts 1-2, and every core 1-1 is respectively by tinned copper wire stranded conductor 1-1-1 be arranged on the outer foam polyolefin insulating barrier 1-1-2 of tinned copper wire stranded conductor 1-1-1 and constitute.The periphery of cable core 1 sets gradually waterstop lapping layer 2 from inside to outside, aluminium-plastic tape keeps off damp screen 3, polyvinyl chloride bonding sheath 4, vertical bag wrinkle steel-tape armouring layer 5 and polyvinyl chloride oversheath 6.
