Description
Technical field
The utility model relates to the cable laying technology, relates in particular to a kind of single-core high-voltage cable drawing head.
Background technology
In high pressure, extra-high-tension cable cable laying operation, how effectively to prevent to intake when cable from laying in cable trough, be the long-term indeterminable problem of cable manufacturer.Traditional single-core high-voltage cable drawing head adopts steel more; Melting the back with lead or tin links together cable and cable drawing head; Reach the purpose of sealing and traction; Because the corrugated aluminium sheath and the steel cable drawing head of single core high pressure, extra-high-tension cable are made up of two kinds of material different, this can cause lead sealing in use can not bear big pulling force, otherwise can cause the lead sealing cracking to come off; Thereby, when in the cable trough water being arranged, promptly can cause the high-tension cable inner inlet, not only delay the duration but also influenced the quality of cable.
The utility model content
To above defective, the utility model provides a kind of in use can satisfy great tractive effort, and the single-core high-voltage cable drawing head of water inlet in can preventing again to use simultaneously is to solve many deficiencies of prior art.
For realizing above-mentioned purpose, the utility model adopts following technical scheme:
A kind of single-core high-voltage cable drawing head; Comprise high-strength aluminum alloy drawing head, aluminium vestlet, traction chapeau de fer and corrugated aluminium sheath; High-strength aluminum alloy drawing head endoporus configuration single-core high-voltage cable conductor and drawing head diameter of bore cooperate corresponding specification list core high-voltage cable conductor diameter again through connecting behind the hydraulic pressure; Said high-strength aluminum alloy drawing head is outside to be connected with the traction chapeau de fer through helicitic texture; High-strength aluminum alloy drawing head skin wherein is with the aluminium vestlet; The conductor insulation periphery is with the corrugated aluminium sheath, and aluminium vestlet wherein covers the corrugated aluminium sheath of single-core high-voltage cable and the corrugated aluminium sheath of aluminium vestlet and single-core high-voltage cable welds through argon arc welding or gas welding.The heat-shrink tube that is positioned at the pad outside is provided with self-adhering type and blocks water filling tape with further waterproof.
The beneficial effect of the described single-core high-voltage cable drawing head of the utility model is: through drawing head aluminium vestlet and single-core high-voltage cable corrugated aluminium sheath are welded; Adopt the drawing head of lead seal structure to compare with traditional some; This drawing head in use can be avoided because of bending or problems such as the excessive lead sealing that causes of pulling force is broken, cracking, cable inner inlet, thereby can effectively guarantee cable installation and service quality; Simultaneously; Because of adopting the argon arc welding solder technology of aluminium; Avoided in making the drawing head engineering, using heavy metal lead and noble metal tin, promptly avoided the pollution of metallic lead and metallic tin, practiced thrift resource again environment; Also greatly reduce simultaneously the cost of manufacture of cable drawing head, thereby to cable manufacturer, to the user, society is all had good economic benefit and social benefit.
