The use of the electrical fittings
Power fittings classification is also varied, can be divided into the following categories:
①. Joint fittings, mainly used in the construction of power fittings overhead power lines, as well as the use of the substation construction of the power station, the general role is to use the connecting fittings to form a string of suspension insulator, and its hanging on the tower, the other role Is to use the connecting fittings to insert a straight line with a vertical cable clip or non-linear plug with the tension clip and insulator string connected together, there are many places can be used to connect the fittings.
Suspension Clamps, such power fittings are mainly used in suspension wire insulator string on the tower there is hanging jumpers on the insulator string.
③ protection fittings, as the name suggests mainly in the role of protection of other electrical fittings, reducing the overhead power line conductors and lightning line vibration amplitude, there is more than 330kv lines and substation insulator string uniform shielding, such products are: shockproof hammer , Interval bar and so on.
④ cable fittings, like DTL. DT. DL a series of copper and aluminum terminals used in distribution equipment inside a variety of round, semi-circular,
Fan-shaped aluminum, copper cables and electrical equipment over-connection, such products in the electrical fittings also played a crucial role.
⑤ equipment fittings, also known as equipment clamp, the main role in the substation bus leads down into aluminum strands and ACSR, so the equipment from the material into the clip on the copper transition equipment and aluminum equipment folder clip Two kinds.
⑥ continuous gold, such power fittings for the overhead power lines conductors, lightning lines and continuous repair and continuity. According to the installation method and the structure is not the same, divided into bolt type, pre-twisted wire, compression type.
⑦ tensile fittings, mainly in the overhead power lines and substations used to fix the wire and lightning lines, and then through the joint fittings with a number of tension insulator connection, or lightning lines and poles connected. Such electrical fittings in accordance with the installation method and structure of the different components can be divided into: bolt type, compression type, and wedge three categories. In addition compression type is divided into two kinds of burst pressure and hydraulic.
⑧ power station fittings, power station fittings, also known as current fittings, which includes substations, power plants to support the installation of electrical installations, fixed some flexible conduit, complex wire and a variety of hard bus and the hardware. This type of power fittings according to the use of the line is divided into slotted, tubular bus, busbar fixed fittings, rectangular.
