The future of wire and cable
2011-11-23 13:46:22

Broadly defined wire and cable are also referred to as cables. A narrow cable is an insulated cable . It can be defined as: an assembly consisting of: one or more insulated wire cores, and the cladding, total protective layer, and outer protective layer they may each have. Cables can also have additional uninsulated conductors

The generator stator uses ultra-high-voltage cables . Round cables will replace rectangular copper bars, which will allow generators to be connected to the grid without transformers, thereby greatly reducing construction costs. According to the optimized design principle, the stator core of large motors has a rectangular slot shape, and the coils or wire rods in the slot also choose rectangular conductors. The distribution of the electric field strength along the circumference is unequal, and its four corners are as high as 9KW / mm. The four straight sides are only 3KW / mm. This will result in a great waste of insulating materials. Cables with a circular cross section do not have this problem, and the electric field strength is evenly distributed. Fundamentally eliminating the problems of concentration of corner field strength, uneven thickness of insulation and non-thinning. This reform can increase the electric field strength from the original 2.5KW / mm to 15KW / mm. This round cable uses industrial mass-produced cross-linked polyethylene insulation, which has a lower cost, but the voltage can be as high as 500KW. There are many factors that affect the voltage selection, such as the connection of the power grid, local regulation details, and the maximum wind energy output per unit surface. Distance, impact on the environment, etc. The output voltage of the generator is increased to the level of the high power grid, and there is no need to go through the step-up transformer to be connected to the grid. Round cable replacements for generators do not require metal shell shielding, although they all use the same materials and solid extrusion insulation process technology, which are also popular standard products on the market.
