Due to its relative simplicity and reliability, the SIP wire has gained its right to life, and is becoming the undisputed leader. Among the possible options for laying an overhead line, priority, most often, will be given to him. What is SIP, how it looks and what types it happens, we considered in one of our articles, namely:. In order to independently lay an overhead line using this conductor, you need to familiarize yourself with some of the nuances, as well as purchase auxiliary equipment and special fasteners. Next, we will consider what kind of fittings are for mounting a SIP cable from a pole to a house.

Auxiliary fittings for mounting a self-supporting insulated wire can be used for different purposes, namely:

• for connecting conductors;
• for hanging the wire on a support or anchor;
• for tensioning the SIP overhead line;
• for connecting contact connections and branches;
• protective auxiliary connections;
• fittings for engagement;
• spiral armature.

Let's consider them in order. The first thing I would like to talk about is the rollers for rolling out the wire.

When pulling an electric line, care must be taken not to damage the insulating layer, avoid dragging along the ground, along tree branches and other surfaces. To do this, they resort to drawing on rollers, which are temporarily mounted on poles, in the places of the future location of the wire.

A galvanized metal tape is used to securely fasten auxiliary equipment to the support.

To tightly wrap around the support, the tensioner pulls the previously cut piece of tape around the post, compresses the bracket, tightly fixing it, and cuts off the excess tape.

Mounting hooks are used to perform quick installation of various SIP fittings on a support, pillars and facades of buildings. They differ in the type of fastening.

For smooth cutting of metal tape, high-quality scissors are useful, leaving no distortions, sharp edges and edges. They allow you to cut with one hand quickly and efficiently, which is certainly appreciated when working at height in cramped conditions.

To compensate for torsion and prevent loops on the CIP wire, as well as to prevent twisting, you can use a device such as a swivel, which is used during installation.

In order to roll the wire over the rollers, it is necessary to stretch the cable along them in advance and connect them to the cable, avoiding damage and knots. This can be done with the help of special tightening stockings. The weaving of the stocking is made in such a way that when it is pulled, a large contact area is created and the insulation of the conductor is not damaged.

A winch is used to tension the wires and eliminate the sag of the overhead line. The use of this device in conjunction with a dynamometer allows you to correctly install the stretched wire of the overhead line.

For suspension and fixation of the stretched conductor, special mounting clamps are used. When using SIP with an isolated carrier neutral, a thunder frog clamp is used.

It is made of environmentally friendly material. Also, when installing SIP, we will need anchor and supporting reinforcement, depending on the place of use (support or building facade) and other sections of the overhead line and branches from it.

Before installing taps on the wire, it is necessary to separate the core to be prepared from the CIP bundle. To do this, there is a phase separator - a wedge of a special shape that diverts the core to the desired distance, facilitating the installation of branch clamps.

To connect to the SIP wire, two types of clamp adapters are used. Branching and piercing clamps. First are used for trunk equivalent branches. It consists of a compression of three plates, between which the current-carrying conductors stripped of insulation are clamped. It is also called "nut". We talked about how to use in a separate article.

To connect a branch from the main is used. When choosing clamps, it is necessary to know the cross section of the main and branches, based on this, make a choice.

For crimping the lugs, the ends of the SIP wire, which are connected to the input or accounting board, you may need a press for crimping the lugs and special dies. With this device, the contact of the core with the tip is obtained with the highest quality.
