Abstract
The utility model provides a signal transmission cable for coal mines, comprising five pairs of dual-strand conductors; a polyethylene insulating protective layer is arranged outside each strand; an elliptic protective layer is wrapped outside a dual-strand; one pair of dual-strand out of five pairs of dual-strand is arranged at the center; the remaining four pairs of dual-strands are arranged around the center; an aluminium-polyethylene gluing layer is wrapped outside the five dual-strand pairs, and is externally provided with a low-density polyethylene sheath layer which is externally provided with a steel wire sheath layer; and the steel wire sheath layer is externally provided with a PVC (polyvinyl chloride) sheath. One pair of the five dual-strand pairs is a spare dual-strand; therefore, when one pair of the four frequently-used dual-strand pairs is damaged, the spare dual-strand can be used for replacing the damaged dual-strand. During the manufacturing process, the color of the spare dual-strand and the color of the other four dual-strand pairs can be distinguished for identification. The steel wire sheath layer can improve the hardness and the tensile performance of the cable to maximum degree.
Description
Technical field
The utility model patent relates to a kind of construction of cable, specifically the colliery signal-transmitting cable.
Background technology
The occasion that use with signal-transmitting cable in the colliery is more abominable, and than common cable, the requirement of strength of this class cable is very high, needs corrosion-resistant, rub resistance, acid-fast alkali-proof performance all very strong, also needs stronger stretch-proof performance.Owing to accident occurs through regular meeting in the colliery, cause the cable can't transmission signals.At this moment need some standby performances of cable are developed.
The utility model content
The purpose of this utility model provides a kind of colliery signal-transmitting cable, in the various performances that guarantee cable, increases the alternate configuration design of cable.
The purpose of this utility model is achieved through the following technical solutions.
The colliery signal-transmitting cable; comprise five pairs of twisted pair conductor; all there is the polyethylene insulation protective layer outside of every twisted wire; external packets at twisted-pair feeder is covered with the oval-shaped protective layer of one deck; there is a pair of twisted-pair feeder to be positioned at the center in five pairs of twisted-pair feeders; all the other four pairs of twisted-pair feeders are around center arrangement; external packets at five pairs of twisted-pair feeders is covered with the aluminum-polyethylene tack coat; the outside of aluminum-polyethylene tack coat is one deck low density polyethylene (LDPE) sheath; in the outside of low density polyethylene (LDPE) sheath is the layer of steel wire armour, is pvc sheath in the outside of wire armoring layer.
Have in five pairs of twisted-pair feeders a pair of for standby twisted-pair feeder, in four pairs of twisted-pair feeders commonly used, a pair of damage is arranged like this in, standby twisted-pair feeder can be taken over use.The color of the color of standby twisted-pair feeder and other four pairs of twisted-pair feeders is carried out distinguishing identifier in manufacture process.And the wire armoring layer can improve the hardness and the stretch-proof performance of cable to greatest extent.
Description of drawings
With embodiment the utility model is described in further detail with reference to the accompanying drawings below.
Fig. 1 is the structure chart of colliery described in the utility model with signal-transmitting cable.
Embodiment
As shown in Figure 1; the colliery signal-transmitting cable; comprise five pairs of twisted pair conductor 1; all there is polyethylene insulation protective layer 2 outside of every twisted wire; external packets at twisted-pair feeder is covered with the oval-shaped protective layer 3 of one deck; there is a pair of twisted-pair feeder to be positioned at the center in five pairs of twisted-pair feeders; all the other four pairs of twisted-pair feeders are around center arrangement; external packets at five pairs of twisted-pair feeders is covered with aluminum-polyethylene tack coat 4; the outside of aluminum-polyethylene tack coat 4 is one deck low density polyethylene (LDPE) sheath 5; in the outside of low density polyethylene (LDPE) sheath 5 is layer of steel wire armour 6, is pvc sheath 7 in the outside of wire armoring layer 6.
Have in five pairs of twisted-pair feeders a pair of for standby twisted-pair feeder 8, in four pairs of twisted-pair feeders commonly used, a pair of damage is arranged like this in, standby twisted-pair feeder 8 can be taken over use.The color of the color of standby twisted-pair feeder 8 and other four pairs of twisted-pair feeders is carried out distinguishing identifier in manufacture process.And the wire armoring layer can improve the hardness and the stretch-proof performance of cable to greatest extent.
