The use of self-supporting wires in modern times is becoming ubiquitous. They withstand a serious load of 35 kV. With the help of SIP, electricity is supplied to buildings and structures for various purposes. Appropriate fittings are required for wiring. An important component in this case is the branch clamp. Using these products, auxiliary wires are connected to the main line.
Where they are used
Clamp for SIP provides the consumer with a constant supply of electricity. When connecting the main line to an electrical source, the supply must be connected directly to the power line. Clips provide safety and reliability of connections. Products belong to special fittings with additional insulation. Accordingly, the insulating layer is not removed from them, so the installation of wires is carried out in a short time.
Deviations from the main electrical line are created when using branch clamps. At the same time, connections are made to street lighting devices, shields in residential buildings, meters, grounding, automatic industrial units, etc.
Varieties
The most popular types of branch clamps are protected from penetration moisture and sealed. Contact is created using special plates equipped with pyramidal teeth and a shear head. Depending on the section of the SIP and the clamp model, the moment of failure is in the range from 9 to 20 N. If you are interested in this topic, then on the site https://sip2a.ru/blog/ you can find a lot of useful information about wires, supports, metal structures of power lines, etc.
Clamps are divided into categories in according to the characteristics:
type of wire connection;
section dimensions;
body protection;
number of bolts.
How to install and dismantle
Application of sealed clamps are in demand when connecting under voltage. In this case, the plate is not in contact with the bolt and shear head. For installation, it is required to have a torque wrench, with which the required tightening force is calculated, since the teeth of the contact plate must not be deformed. When dismantling, the clamps are removed or removed with wire cutters. In this case, the second head is used. Reuse of clamps is not provided, the parts are disposable.
