Cable Conductor Insulation Supply Equipment

The Cable is the device that connects the cable. If the cable connector is a device connected to the cable, it will allow the circuit to flow unimpeded, ensuring interface or phase insulation, sealing and mechanical protection. The cable terminals are installed at the end of the cable line to ensure the electrical connection of the power grid or other electrical equipment and to provide equipment for the insulation of cable conductors. Cable accessories are general terms for the installation or production of components and materials for cable connections and terminals. The accessories here refer to parts and materials. Cable and cable accessories processing plant, and Cable shape in case of site, and manual operation, on-site environmental conditions vary greatly, operation skilled workers, so the quality of cable connectors is not only related to the quality of cable accessories, but also in the installation conditions. Cable accessories, with its uniqueness, whether it is a shrinkable cable accessory, a shrink cable accessory, or a prefabricated cable accessory, a complete product before installation, there is no perfect cable accessory product also just a combination of some parts and materials, only these parts of the material and installed in the cable line according to the process requirements, Complete certain cables for cable accessories, cable accessories and Cable differences, which are wired.

Differences between cable accessories and Cableers

Cable accessories, with its uniqueness, whether it is a shrinkable cable accessory, a shrink cable accessory, or a prefabricated cable accessory, a complete product before installation, there is no perfect cable accessory product also just a combination of some parts and materials, only these parts of the material and installed in the cable line according to the process requirements, Complete cable accessories for a certain cable, this is the Cable.

The cable plus AC voltage, there is current flow, when the voltage amplitude and frequency must be, the size of the capacitance current is proportional to the cable capacitance (Cx). For ultra-high voltage cables, the current of the capacitor may reach a value comparable to the rated current, and become an important factor in limiting cable capacity and transmission distances. So the capacitance of the cable is also one of the main electrical performance parameters of the cable.

In an AC electric field, the insulator in the cable is present due to leakage current and various polarization, dielectric loss is formed by dielectric loss factor or loss angle tangent (tan), which not only wastes electrical energy, but also heats the dielectric (insulator) and accelerates insulation aging, so TAN is one of the main parameters of the cable.

Through the measurement of capacitance and loss factor, it can be found that insulation is damp, insulation layer and shielding layer fall off and so on, so that both capacitance and Tan are measured in cable manufacture or cable operation. Measurements of high-voltage cables, CX and Tan are carried out under working conditions, that is, under high frequency pressure, usually using a high-pressure Xilin bridge, and this year has started to use a current-ratio transformer bridge.
