Description

A water-blocking overhead insulated cable for smart energy

technical field

The utility model relates to a water-blocking overhead insulated cable for smart energy.

Background technique

During the construction and installation of overhead insulated cables, the ends are prone to water ingress, and are not easy to volatilize, which seriously reduces the service life of the cables. Especially in areas with large spans and heavy ice, rain and snow, it is difficult to meet the needs of the project using traditional overhead insulated cables. Compared with traditional aerial insulated cables, carbon fiber composite core water-blocking overhead insulated cables have the advantages of light weight, strong water-blocking, high strength, low line loss, small sag, high temperature resistance, corrosion resistance, and environmental affinity, which significantly reduces The installation and maintenance costs of tower poles and cables effectively ensure the normal operation of the power grid.

The purpose of the utility model is to overcome the limitations of the application of carbon fiber composite core conductors and water-blocking overhead insulated cables, and provide an overhead insulated cable that can achieve water-blocking effects and is suitable for large-span heavy ice, rain and snow areas.

The technical solution for realizing the purpose of this utility model is a water-blocking overhead insulated cable for smart energy, which consists of a composite core, a water-blocking conductor, a conductor shielding layer and a weather-resistant insulating layer from the inside to the outside; the water-blocking conductor includes at least two layers of wires and A water-blocking strip longitudinally wrapped between adjacent conductors; the composite core includes a central layer and a cladding layer connected by resin; the central layer is carbon fiber, and the cladding layer is glass fiber.

A water-blocking filling is provided between the outermost wire of the water-blocking conductor and the conductor shielding layer.

Water-blocking filling is filled with water-blocking yarn or filled with water-blocking powder.

The water-blocking conductor includes two layers of wires, and the water-blocking tape is longitudinally covered between the two layers of wires.

The wires of each layer have the same or different shapes, and the cross-sectional shape is circular, trapezoidal, Z-shaped or S-shaped.

The conductor shielding layer is cross-linked polyethylene or non-cross-linked polyethylene; the weather-resistant insulating layer is polyethylene, polyvinyl chloride or cross-linked polyethylene.

Adopting the above-mentioned technical scheme, the utility model has the following beneficial effects: (1) The utility model adopts a composite core of carbon fiber coated with glass fiber as the load-carrying core, which greatly reduces the weight of the cable and reduces sag, Increase the span, effectively reducing the cost of the tower and installation.
