Abstract
The utility model provides a novel mining video monitoring cable which has reasonable, compact and prudent structure, small volume, simple producing and manufacturing processes and very convenient use and maintenance, wherein the innermost layer is a tinned conductor with the impedance being 50 omega and 75 omega; an insulating layer is arranged outside the conductor; a shielding layer is arranged outside the insulating layer; an antiflaming PVC inner protection layer is arranged outside the shielding layer; a galvanized steel wire weaved armor layer is arranged outside the inner protection layer; and a low-smoke and low-halogen PVC jacket is arranged outside the armor layer. The novel mining video monitoring cable can be applicable in a video monitoring system under a mine as a connecting line used for transmitting video signals.
Description
Technical field
The utility model relates to a kind of cable, is specifically related to a kind of new type mining video monitoring cable.
Background technology
Along with the modernization construction process is accelerated day by day, science and technology constantly promotes the prosperous and development of all trades, continuous development of underground mine resource in recent years and deep exploitation seem greatly active, novel exploring equipment automaticity is more and more higher, and the new technology of exploration, new technology are used fully and promoted.The particularly injection of down-hole computer network-based video monitoring technique and watch-dog.But because subsurface environment and abominable, the ordinary video cable is owing to be subjected to humidity corrosive gas friction and the frequent collision and the electromagnetic interference of charging equipment etc. influence, reduce the dielectric strength of cable greatly, signal attenuation causes analog signal transmission weak, unstable greatly, and sensitivity reduces image fault.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, provides that a kind of product structure is reasonable, compact, careful, volume is little, and manufacturing process is simple, and operation and maintenance is new type mining video monitoring cable extremely easily.
The technical solution of the utility model is: a kind of new type mining video monitoring cable, its innermost layer is the tinned conductor of impedance 50 Ω, 75 Ω, conductor is provided with insulating barrier outward, insulating barrier is provided with screen, screen outward and is provided with the flame-proof PVC sheath outward, sheath is provided with zinc-coated wire braiding armour outward, and armour is provided with the PVC Sheathing Compound sheath outward.
The utility model is applicable under the mine in the video monitoring system, as the connecting line of transmission video signal.
Beneficial effect: the utlity model has functions such as flame-proof environmental protection, anti-interference, anti-collision, protection against the tide, have performances such as the insulation lossy medium is low, decay is little, the signal transmission is quick, stable, reliable especially.
Description of drawings
Accompanying drawing is a structural representation of the present utility model.
