Abstract
The invention discloses a cable for coal mine monitoring. The cable comprises five copper conductors, an insulation layer, a shielding net, a polyester belt and a rubber layer. The copper conductors are wrapped by the insulation layer. The insulation layer is wrapped by the shielding layer. The polyester belt wraps the shielding net. The rubber layer wraps the polyester belt. The rubber layer is made of polyvinyl chloride. Tinning treatment is carried out on the copper conductors. Electromagnetic radiation protection is carried out on the cable, electromagnetic interference is shielded, it is ensured that an instrument normally works, and electromagnetic leakage is avoided; electromagnetic signals are effectively shielded and restrained through a display window. According to the optical performance, the light transmittance ranges from 50% to 70%, the shielding effect ranges from 50 dB to 60 dB, and the frequency ranges from 10 MHz to 1.5 GHz.
Description
Technical field
The present invention relates to a kind of cable, in particular a kind of colliery supervision cable.
Background technology
Cable is normally by the cable of the similar rope of several or several groups wire strandings, and often organize mutually insulated between wire, and be often twisted into round a center, whole outside is surrounded by the cover layer of high-insulation.Multi rack is located at aerial or is contained in underground, the bottom, for telecommunication or electric power conveying.
Be used as the cable monitoring cable, the requirement shielded its signal disturbing is very high, and requirement can electromagnetism interference.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, provide a kind of colliery supervision cable, the demand of cable fire can be met.
The present invention is achieved by the following technical solutions, the present invention includes five copper conductors, insulating barrier, gauze screen, polyester belt, rubber layers, described copper conductor outer cladding insulating barrier, insulating barrier is wound around gauze screen outward, polyester belt is wrapped in outside gauze screen, rubber layer is coated on outside polyester belt, and described rubber layer is that polyvinyl chloride is made, zinc-plated process on copper conductor.
As one of optimal way of the present invention, between the gauze screen of described five copper conductors and polyester belt, fill out the flame resistant filler rope establishing glass fibre to make.
As one of optimal way of the present invention, the cross section of described copper conductor is circular, triangle or fan-shaped.
As one of optimal way of the present invention, described gauze screen is that stainless steel is made.
As one of optimal way of the present invention, described gauze screen is copper mesh, described copper mesh outer cladding tin coating.
As one of optimal way of the present invention, described gauze screen string diameter is 0.025 ~ 0.05mm, nets thick 0.05 ~ 0.1mm.
The present invention carries out zinc-plated process on copper conductor, copper wire can be prevented to be oxidized, keep good continuity test, be convenient to conductor and conductor, conductor welds with instrument, has good welding performance, copper has catalytic action to the aging of rubber, and isolation copper and rubber, delay rubber aging.
The present invention has the following advantages compared to existing technology: Cable Electromagnetic Radiation protection of the present invention, and shield electromagnetic interference, ensures that instrument and equipment normally works, prevent electromagnetic leakage: effectively shielding suppresses the electromagnetic signal by display window.Optical property: light transmittance 50% ~ 70%, shield effectiveness: 50 ~ 60dB (frequency range 10MHz ~ 1.5GHz).
