Abstract
A flexible cable joint used in a high and cold area relates to a cable joint, solving problems that first-aid repair on underground power cables by workers is difficult to carry out in high and cold areas and normal electricity use in power supply regions of fault cable lines is easily affected. The cable joint comprises a copper core, a first semiconductive layer, an insulating layer, an ethylene propylene rubber layer, a second semiconductive layer, a shielding layer, a thermoplastic protective insulating layer and a terminal. The copper core is composed of a plurality of copper wires. The first semiconductive layer is coated outside the copper core. The insulating layer is coated outside the first semiconductive layer. The ethylene propylene rubber layer is coated outside the insulating layer. The second semiconductive layer is coated outside the ethylene propylene rubber layer. The shielding layer is coated outside the second semiconductive layer. The thermoplastic protective insulating layer is coated outside the shielding layer. The copper core is connected with the terminal. The flexible cable joint is used to repair cables in high and cold areas.
Description
Technical field
The utility model relates to a kind of cable joint.
Background technology
The extremely frigid zones underground power cable damages at present, can't be for joining when power supply, can only take traditional approach to solve, namely search the Method of Cable Trouble Point position, handle to account for and dig the road formality, excavate high alpine frost soil underground cable fault point, make butt joint and withstand voltage test and can restore electricity after qualified with instrument.Usually each link adopts the repairing of working continuously of rotational personnel's mode, needs just can restore electricity in about 48 hours, if but Method of Cable Trouble Point difficulty search in the situation, just need to take the more repairing time, even all can't find position of failure point in the sometimes a few days.The normal electricity consumption that this has had a strong impact on failure cable line powering zone user causes a large amount of electricity sales amount of power supply enterprise's loss.
The utility model content
The purpose of this utility model provides a kind of extremely frigid zones flexible cable joint, damages the problem that the staff rushes to repair difficulty and easily affects failure cable line powering zone user's normal electricity consumption to solve present extremely frigid zones underground power cable.
The utility model is to solve the problems of the technologies described above the technical scheme of taking to be: the described cable joint of present embodiment comprises the copper core; the first semi-conductive layer; insulating barrier; the ethylene-propylene rubber layer; the second semi-conductive layer; screen; thermoplastic protection insulating barrier and terminal; the copper core is made of many copper wires; the first semi-conductive layer is wrapped in the outside of copper core; insulating barrier is wrapped in the outside of the first semi-conductive layer; the ethylene-propylene rubber layer is wrapped in the outside of insulating barrier; the second semi-conductive layer is wrapped in the outside of ethylene-propylene rubber layer; screen is wrapped in the outside of the second semi-conductive layer; thermoplastic protection insulating barrier is wrapped in the outside of screen, and the copper core is connected with terminal.
The utlity model has following beneficial effect: winter is cold, and the power cable damage is serious, and two cables are out of service, and can't adopt this cable joint to carry out provisional repairing power supply for the particularly urgent situation of joining, and can reach the purpose of fast recovery of power supply.
Description of drawings
Fig. 1 is overall structure schematic diagram of the present utility model, and Fig. 2 is the structural representation of embodiment one, and Fig. 3 is the structural representation of embodiment two.
Embodiment
Embodiment one: present embodiment is described in conjunction with Fig. 1; the described cable joint of present embodiment comprises copper core 1; the first semi-conductive layer 2; insulating barrier 3; ethylene-propylene rubber layer 4; the second semi-conductive layer 5; screen 6; thermoplastic protection insulating barrier 7 and terminal 8; copper core 1 is made of many copper wire 1-1; the first semi-conductive layer 2 is wrapped in the outside of copper core 1; insulating barrier 3 is wrapped in the outside of the first semi-conductive layer 2; ethylene-propylene rubber layer 4 is wrapped in the outside of insulating barrier 3; the second semi-conductive layer 5 is wrapped in the outside of ethylene-propylene rubber layer 4; screen 6 is wrapped in the outside of the second semi-conductive layer 5; thermoplastic protection insulating barrier 7 is wrapped in the outside of screen 6, and copper core 1 is connected with terminal 8.
Embodiment two: in conjunction with Fig. 2 present embodiment is described, the cable joint of present embodiment also comprises Rain-proof skirt 9, and described Rain-proof skirt 9 is hollow round table shape, and Rain-proof skirt 9 is sleeved on the outside of thermoplastic protection insulating barrier 7 and the two makes one.Other execution mode is identical with embodiment one.
Embodiment three: in conjunction with Fig. 3 present embodiment is described, the cable joint of present embodiment also comprises elbow type head 10, and elbow type head 10 is contained in the end of thermoplastic protection insulating barrier 7 and the two closely cooperates.Other execution mode is identical with embodiment one.
Operation principle: when two cables damage, can't be with and join, if by the normal method repairing, owing to weather in severe winter, estimate that time time spent is long, this will greatly affect power supply quality, adopt the interim power supply plan of multi-function head flexible cable.Adopt on the ground two sections (100 meters every section) multi-function head flexible cables to connect, realize temporarily power supply.
Rush Repair Scheme is implemented the technical staff of cable center according to site contour, arrange Rush Repair Scheme and safety measure, using bucket arm crane that flexible cable is carried out wall hangs, (on the cable every 5 meters setting " halt, Keep Clear-High Voltage " sign) laid on ground, the employing channel-section steel that can't suspend in midair for the pavement part covers, preventing that the pedestrian from trampling with automobile rolls, and in the hazardous location personnel's monitoring is set, and the time spent of all working is shorter.
Again the two cables of fault are carried out trouble shoot, cable trough excavation, make the first-class work of indirect after the energising, behind the recovery normal power supply, flexible temporary cable is removed.After adopting the utility model to power, restore electricity in the short time temporarily, keep in repair under the section between at this moment, save a large amount of maintenance time.
