Can, the propagation rate of signal etc. propose the requirement of higher.Particularly apply and contain in oil, chemical industry, weaving and colliery etc.
There is the data cable in the environment of explosive gas mixture, it is necessary to have intrinsic safety characteristic.And existing data transfer electricity
The aspect of performance such as cable, its low capacitance, low inductance performance, transmission stability, wearability, temperature use scope, flexibility also exists
Deficiency, it is difficult to meet growing requirement.
Utility model content
The purpose of this utility model is to provide a kind of intrinsic safety type flexible data transmission cable, which has excellent
Essential safety, low capacitance, low inductance, high fire-retardance, the features such as anti-interference, dielectric loss is low, signal transmission capabilities are strong, can be reliably
Transmit signal of communication, while soft easily construction.
The technical solution of the utility model is：Including cable core, and set gradually from inside to outside on the outside of cable core belting layer,
Flame-retardant layer, total shielded layer and oversheath；The cable core is twisted by two groups of insulated wire cores and two gasket for packings；The insulated wire
Core forms conductor thread core after the crosslinked polyetylene insulated layer pair twist on conductor is extruded in by conductor and closely, on conductor thread core according to
Secondary setting lapping layer, aluminium-plastic tape subitem shielded layer and polyester film lapping layer；Subitem shielded layer and the lapping layer it
Between more tinned copper wire drainage threads are set.
The conductor is twisted by several high-quality soft circular copper wires.
The belting layer is high fire-retardance polyester belt lapping layer.
The flame-retardant layer is wrapped for Halogen glass fiber tape bilayer, every layer of cap rate >=60.
Total shielded layer is tinned copper wire woven shield, using the proof copper-wire braided of diameter >=0.1mm, count
≥85%。
The oversheath is extruded by fire retardant semi-conductive polyolefin plastics and formed.
The beneficial effects of the utility model are：
1st, the utility model conductor uses high-quality soft circular copper wire, and insulating layer is extruded using cross-linking polyethylene materials, makes product
With excellent intrinsic safety characteristic, low capacitance, low inductance, superior electrical property.
