Abstract
The utility model relates to a high strength clamp for three-core cable middle part. The clamp comprises an upper clamp body, and a lower clamp body, wherein the upper clamp body is connected with the lower clamp body to form a through hole matched with a three-core cable. The high strength clamp for three-core cable middle part has the advantages over the prior art of flexibility, convenience, and long service life.
Description
Technical field
The utility model relates to a kind of cable and uses anchor clamps, especially relates to the middle high strength anchor clamps of using of a kind of three-core cable.
Background technology
Along with electrical network constantly enlarges and renewal; The design of high pressure and ultrahigh voltage power cable tunnel and application increase day by day; The electric pressure of well-known cable is high more, and its line loss is more little, and superhigh pressure, length, heavy in section, variation and high reliability are current power cable technology trends.In transformer station's cable floor, cable trough, cable tunnel and other power cable structures, be used for supporting the support with attached cable, installation and operation has crucial effect to cable.All adopt the steel construction cable bearer in the common engineering; And cooperation clamps cable; Aspect the use of cable cleat, during laying, prior cable mostly adopts band, plastic clamp, traditional fixture rail or common aluminum alloy anchor clamps, can not effectively retrain cable; Cable is axially adopted vertically all solutions well of electric power influence between living slippage and cable, and this anchor clamps have following problem:
(1) environmental suitability is poor: the intensity and the decay resistance of existing anchor clamps are all poor, are not suitable in the more abominable tunnel of environment, using.
(2) if be metal fixture, be used for high voltage single-core cable, when cable jacket damages, may form ground connection circulation or produce gap discharge, cause cable jacket further to damage through anchor clamps.
(3) be in operation because the effect of alternating electromagnetic field; Can on electroconductive magnetic medium metal fixture, produce tangible eddy current loss and magnetic hysteresis loss, cause backing temp to raise, thereby the cable jacket surface temperature is raise; The medium thermal resistance increases on every side, influences the cable transmission capacity.
Summary of the invention
The purpose of the utility model is exactly to provide a kind of three-core cable flexible, that the life-span is long the middle high strength anchor clamps of using for the defective that overcomes above-mentioned prior art existence.
The purpose of the utility model can realize through following technical scheme: use the high strength anchor clamps in the middle of a kind of three-core cable; It is characterized in that; These anchor clamps comprise upper clamp and lower clamp, and described upper clamp and lower clamp are connected to form a through hole, and this through hole and three-core cable are complementary.
The lateral wall of described upper clamp is arch-shaped structure; Its madial wall top is semicircle shape; Be complementary with an outside diameter of cable in the three-core cable, the both sides, bottom respectively with the lower clamp madial wall connect into three-core cable in two other outside diameter of cable be complementary circular-arc.
Described lower clamp is wavy; The lower clamp both upper ends thereof is provided with contiguous block b; This contiguous block is provided with connecting hole b, and two ends, described upper clamp bottom are provided with the contiguous block a that is complementary with said contiguous block b, and contiguous block a is provided with connecting hole a; Bolt a passes connecting hole a and connecting hole b, connects upper clamp and lower clamp.
The described contiguous block a outside is provided with the barb that prevents that bolt a from sliding.
Two ends, described lower clamp bottom are provided with fixed block, and this fixed block is provided with fixing hole, and bolt b passes the fixing hole stationary fixture.
Be provided with rubber packing in the described through hole.
Described rubber packing is the black neoprene.
Compared with prior art, the upper clamp of the utility model anchor clamps and lower clamp are the split setting, and the through hole and the three-core cable external diameter that connect back formation through bolt are complementary; Three cables of three-core cable are adjacent in twos; Be the trapezoidal shape stack, fixing hole is set on the lower clamp, because fixing hole has certain length; Therefore can adjust its horizontal level within the specific limits, flexible.
