Abstract
The utility model discloses a wisdom energy is with overhead insulated cable that blocks water, from interior to exterior are compound core, the conductor that blocks water, conductor shield and weatherability insulating layer in proper order, the conductor that blocks water includes at least two -layer wire and vertical the block water area of cladding between adjacent wire, compound core includes central core and the coating of being connected by the resin, the central core is the carbon fiber, and the coating is glass fiber. The utility model discloses an outer cladding glass fiber's of carbon fiber compound core comes as bearing the weight of the sinle silk, great reduction the weight of cable, reduce the arc and hang down, increase the span, effectual tower pole and the mounting cost of having reduced.
Description
Technical field
This utility model relates to a kind of wisdom energy water blocking overhead insulated cable.
Background technology
Aerial insulated cable termination during construction and installation easily intakes, and the service life of the most volatile serious reduction cable.Especially in Great span, heavy ice sleet area, traditional aerial insulated cable is used to be difficult to meet the needs of engineering.Carbon fiber complex core water blocking overhead insulated cable have compared with conventional overhead insulated cable lightweight, block water by force, the advantage such as intensity is big, low line loss, sag are little, high temperature resistant, corrosion-resistant and environment is affine, significantly reduce tower bar and maintenance cost installed by cable, electrical network has been effectively ensured properly functioning.
Utility model content
The purpose of this utility model is to overcome carbon fiber composite core wire and the limitation of water blocking overhead insulated cable application, it is provided that a kind of can realize the aerial insulated cable that block-water effect is suitable for again the heavy ice sleet area of large span.
Realizing this utility model purpose technical scheme is a kind of wisdom energy water blocking overhead insulated cable, is followed successively by composite core, water-blocking conductor, conductor shield and weatherability insulating barrier from the inside to the outside；Water-blocking conductor includes at least two layer conductors and the waterstop being longitudinally coated between adjacent wires；Composite core includes central core and the clad connected by resin；Central core is carbon fiber, and clad is glass fibre.
The filling that blocks water is set between the outermost wire of water-blocking conductor and conductor shield.
Block water and be filled to fill water blocking yarn or filling and block water powder.
Water-blocking conductor includes two layer conductors, is longitudinally coated with waterstop between two layer conductors.
Each layer conductor shape is identical or different, and cross sectional shape is circular or trapezoidal or Z-shaped or S-shaped shape.
Conductor shield is cross-linked polyethylene or non-crosslinked polyethylene；Weatherability insulating barrier is polyethylene, polrvinyl chloride or crosslinked polyethylene.
Have employed technique scheme, this utility model has following beneficial effect: (1) this utility model uses the composite core of carbon fiber outer cladding glass fibre to be used as carrying core, the weight of cable is greatly reduced, reduce sag, increase span, be effectively reduced tower bar and mounting cost.
(2) this utility model uses multi-layer conductor leads, between adjacent wires, longitudinally cladding blocks water and brings the effect realizing conductor longitudinal water-blocking, material water-proof material is also filled up between outermost layer wire and screen layer, can effectively stop water inlet and vertical migration in cable, avoid cable inner conductor to be corroded, extend cable and use the time, significantly reduce cable maintenance cost.
