Abstract
The utility model belongs to the field of a power cable, and more specifically relates to a water-resistant conductor used for an undersea cable. The water-resistant conductor comprises a central conductor and single conductors. The water-resistant conductor is characterized in that the central conductor and the single conductors are intertwisted regularly to be cylindrical; during the intertwisting process, a one-side semiconductor water-resistant band with high water resistance is wrapped in a longitudinal manner outside the central conductor, the single conductors are wrapped with one-side semiconductor water-resistant bands in a longitudinal manner, and water-resistant yarn correspondingly having the same amount with the single conductors is intertwisted into the single conductors to longitudinally wrap the one-side semiconductor water-resistant bands; and a semiconductor water-resistant binding belt is wrapped on the outermost layer of the water-resistant conductor. The water-resistant conductor used for an undersea cable helps to solve problems that a conventional water-resistant conductor is poor in water resistance and high in maintenance cost.
Description
Technical field
The utility model belongs to the power cable field, is specifically related to a kind of sea electric power cable water-blocking conductor.
Background technology
At present each Utilities Electric Co. is for improving cable operation matter attitude, prolongs cable useful life, stops the generation of water tree, extends to water proof type cable direction, and the market demand just constantly enlarges.Submarine cable since its special environment that lays blocking water of conductor had higher requirement.But traditional water-blocking conductor adds water blocking yarn when only being chosen in conductor strand system, the outer wrapped semiconductive waterstop of conductor, and block-water performance is difficult to reach the requirement of marine environment.
The utility model content
The technical problem that the utility model will solve provides the submarine cable that a kind of block-water performance is high, maintenance time is short and uses water-blocking conductor.
In order to solve the problems of the technologies described above; The utility model provides a kind of submarine cable to use water-blocking conductor; Comprise center conductor and single line conductor, said center conductor and single line conductor be regular be twisted into cylindric, the single face waterstop of the vertical bag of center conductor one deck high water resistant performance in strand system process; Twist into the water blocking yarn of corresponding radical and vertical bag single face semiconductive waterstop the wrapped semiconductor of the outermost layer binding strap that blocks water between every layer with the single line conductor.
It is regular stranded that the primary structure of this product is characterized as employing, takes the suitable coefficient that presses, and reduces the slit between single line; Increase the block-water performance of copper conductor self, this conductor has good vertical block-water performance under the prerequisite that satisfies mechanical performance and electrical property, and the ability long period of soaking is in seawater; Especially impaired at cable, when damage is deep into conductor, can stop or delay to form in the conductor water tree effectively; Avoid whole cable to scrap, need only repair or change impaired part cable, can practice thrift maintenance cost significantly; Shorten maintenance time, reduce loss of outage.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is done further detailed explanation:
Fig. 1 is the structural representation of the utility model.
Embodiment
As shown in Figure 1; The utility model provides a kind of submarine cable to use water-blocking conductor; Comprise center conductor and single line conductor 1, said center conductor and single line conductor 1 be regular be twisted into cylindric, the single face semiconductor waterstop 3 of the vertical bag of center conductor one deck high water resistant performance in strand system process; Go into the water blocking yarn 2 and the vertical bag single face semiconductive waterstop 3 of corresponding radical between every layer with single line conductor 1 strand, the wrapped semiconductor of the outermost layer binding strap 4 that blocks water.
Adopt regular stranded in the conductor strand system process; In the process of each layer single line conductor 1 strand system, vertical bag one deck single face semiconductive waterstop 3 can adopt wrapped mode under the condition that equipment allows; Avoid in the vertical packet procedures because of the single face semiconductor waterstop 3 wrinkling slits that produce; The strand system adds high-performance water blocking yarn 2 simultaneously, and water blocking yarn 2 answers thickness suitable, makes it to fill up the slit between waterstop 3 and the single line conductor 1.The wrapped one deck of conductor outermost layer binding strap 4 that blocks water guarantees the block-water performance of conductor.
Impaired at cable, when damage was deep into conductor, waterstop in the conductor gap and water blocking yarn imbibition stoped seawater along the conductor longtitudinal dispersion.
Above-described only is the preferred implementation of the utility model; Should be understood that for a person skilled in the art; Under the prerequisite that does not break away from the utility model structure, can also make some distortion and improvement, these can not influence effect and practical applicability that the utility model is implemented.
Claims (1)
1. a submarine cable is used water-blocking conductor; Comprise center conductor and single line conductor; It is characterized in that: said center conductor and single line conductor be regular be twisted into cylindric; The single face semiconductor waterstop of the vertical bag of center conductor one deck high water resistant performance in strand system process twists water blocking yarn and vertical bag single face semiconductive waterstop into corresponding radical with the single line conductor between every layer, the wrapped semiconductor of the outermost layer binding strap that blocks water.
