Description

Power transmission cable for wind power generation

Technical Field

The utility model relates to a cable installation technical field specifically is transmission cable for wind power generation.

Background

Cables are generally rope-like cables made by stranding several or groups of conductors, at least two in each group, each group being insulated from each other and often twisted around a center, the entire outer surface being covered with a highly insulating covering. The device is erected in the air or installed underground or underwater for telecommunication or power transmission. In 1832, the sars and retired officer schooling grid buried the telegraph line underground, and the six wires were insulated with rubber and placed in a glass tube, which is the earliest underground cable in the world. The insulated wire is formed by arranging one or more mutually insulated conductive wire cores in a sealed sheath. It may be coated with a protective coating for transmitting, distributing electrical energy or transmitting electrical signals. The difference between the cable and the common wire is mainly that the cable is large in size and complex in structure. The cable is mainly composed of the following 4 parts. Firstly, a conductive wire core: made of a high conductivity material (copper or aluminum). Each core may be formed by twisting a single wire or a plurality of wires according to the requirement of laying and using conditions on the flexibility degree of the cable. Insulating layer: the insulating material used as the cable should have high insulation resistance, high breakdown field strength, low dielectric loss and low dielectric constant. Common insulating materials used in cables are oil-impregnated paper, polyvinyl chloride, polyethylene, crosslinked polyethylene, rubber, and the like. Cables are often classified as insulating materials, such as oil impregnated paper insulated cables, polyvinyl chloride cables, crosslinked polyethylene cables, and the like. Sealing the sheath: protecting the insulated wire core from mechanical, moisture, humidity, chemicals, light, etc. For moisture-sensitive insulation, a lead or aluminum extrusion seal jacket is generally used. Protecting the covering layer: to protect the sealing boot from mechanical damage. Galvanized steel strips, steel wires or copper strips, copper wires and the like are generally used as armor to wrap the armor outside a sheath (called an armored cable), and the armor layer simultaneously plays the roles of shielding an electric field and preventing external electromagnetic wave interference. In order to avoid corrosion of steel belts and wires by surrounding media, they are generally coated with asphalt or wrapped with an impregnated jute layer or an extruded polyethylene or polyvinyl chloride jacket, and cables are classified into power cables, communication cables, control cables, and the like according to their uses. Compared with an overhead line, the cable has the advantages of small insulating distance between lines, small occupied space, no occupation of space above the ground due to underground laying, no influence of pollution of the surrounding environment, high power transmission reliability, and small interference on personal safety and the surrounding environment. But the cost is high, the construction and the maintenance are troublesome, and the manufacture is complicated. Therefore, the cable is mostly applied to dense areas of population and power grids and places with heavy traffic; when the cable is laid in the river, the river and the seabed, the use of large-span overhead lines can be avoided. Cables may also be used where it is desirable to avoid interference of overhead lines with communications and where aesthetic considerations or exposure to objects are desired.
