The best manufacturers of fittings for self-supporting insulated wire for 2020

In the energy sector, self-supporting insulated wires are used, in another way they are called SIP. They have been used in this area for over 40 years because they guarantee reliability, safety and trouble-free operation. Thanks to them, the transportation of electrical energy takes a minimum of time.

The main advantage of such wires is simplicity, because they are several conductors made of aluminum and form a single bundle. For greater safety, each element is equipped with an insulated shell made of polyethylene. Quality hardware must be used to support the entire system. Therefore, the editors of the site "bestx.htgetrid.com/en/" have prepared for you a rating of the best manufacturers of fittings for self-supporting insulated wire for 2020.

What is SIP and its advantage

To understand why such a design requires separate fittings, it is important to know what constitutes a self-supporting insulated wire. Most often it is a two or four-core cable, which is twisted into a bundle, and is made of an aluminum alloy. The insulating material is made of polyethylene or similar thermoplastic material. 90% of the products have one zero core, where there is a special steel core. The rest of the parts are phase, they differ in color, but most often they represent black wires, which are divided by the cross-sectional area.

The main advantage is that all the conductors are connected into a single structure, which prevents the risk of a short circuit in strong winds, and also minimizes the risk of breakage due to frozen pieces of ice in winter. Thanks to this, wires can be used in any area; neither the sun, nor fire, nor rain will spoil the high-quality transportation of electrical energy. In addition, the cable is highly resistant to mechanical stress.

In stores, you can find 5 types of SIP:

• SIP-1. The model is made to work with a voltage of 380 V. There are 3 conductors made of aluminum alloy, the insulating layer is polyethylene. Possesses high resistance to sunlight. There are 4 cores (zero), it is made of a steel core, it has no insulation.
• SIP-2. Unlike the previous version, here each core has a reliable insulating layer.
• SIP-3. It is a single-core wire made of steel-aluminum; for insulation, a light-stabilized material was used, which was connected to polyethylene.
• SIP-4. Each core has a strong insulation that is resistant to thermal effects. There is no supporting core.
• SIP-5. The model is practically no different from the previous version, the only difference is that the insulation is made of cross-linked polyethylene.

It is important to know when the letter T is present at the end of the wire marking, this indicates that the insulation used is resistant to temperatures. Prefix A - the zero core has special insulation. The H symbol indicates the material from which the current-carrying conductors are made, most often it is aluminum. The rated voltage of almost all SIPs is the same and amounts to 1 kV, only for the SIP-3 model it reaches 35 kV.

The main advantages of SIP include:

• Easy installation, the main thing is that good fittings are present;
• Due to the fact that a person does not need to spend money on additional supports, this saves money on connection and maintenance;
• It is possible to mount directly on the wall of the house, as the increased insulation will exclude damage to the wires;
• The minimum service life reaches 30 years;
• Using SIP, you can forget about the loss of electrical energy;
• Wet snow, as well as ice, will no longer create additional problems;
• To lead the wire into the house, this does not require turning off the working electrical installation; everything is done quickly and easily.

In addition, such a cable is capable of operating at temperatures from -60 to +50 degrees, which is a positive point. To carry the self-supporting insulated wire into the house, it is enough that the temperature does not drop below -20 degrees, then the work will take place without problems.

SIP fittings, what is important to know?

Fittings for self-supporting insulated wires are a unique product that is designed to fulfill three main tasks:

• Fixing the wire on the wall of residential buildings or industrial facilities;
• Combining cables into one power system;
• Separation of conductors for conducting in several buildings.

The main function of self-supporting insulated wire reinforcement is to ensure reliable and safe electrical transmission through overhead lines, as well as through light sources, regardless of the maximum voltage. For the production of the structure, special materials are used that are highly resistant to various mechanical loads, and are also not subject to corrosion and other natural phenomena. If the manufacturer uses good metal to create fittings, then the minimum service life will be 50 years, with no special maintenance required.

You should be aware that the structure is manufactured in accordance with technical documents and generally accepted standards, which were developed in 1996 and have not undergone significant changes since then. The regulatory documents indicate: from what material the equipment is made, a number of unacceptable errors, technical specifications and similar criteria.

The development of such conditions was carried out by the European Committee for the Standardization of Electrical Equipment. This knowledge will help the buyer in the event that he doubts the honesty of the seller, then he has the right to demand a document to make sure that the specified characteristics are in full compliance with the applicable standards.

The main elements of reinforcement self-supporting insulated wire

The structure is included in several main groups, without which it is impossible to perform high-quality installation.

Branching piercing clamps (ZPO)

The element is designed for fixing without axial load, and also serves as the main product for branching cables and facilitates the connection of subscriber wires. The piercing takes place thanks to the teeth of the contact plates, which are exposed and create tight electrical contact.

The correct tightening torque is responsible for the high reliability of the connection. Installation is carried out on a working power line, it is not necessary to turn off the power. Due to the good design, moisture is not a problem. The insulation also does not need to be removed.

Intermediate suspension kit (gearbox)

This element is designed to support the anchorage of the insulated carrier conductor. It is made of a polymer clip, which has good insulating properties. Differs in high resistance to weather and climatic conditions.For greater reliability, the bracket is made of aluminum alloy.

Intermediate support clamp (PPZ)

The part is used to connect the insulated neutral of SIP up to 1 kV. It is used for suspending a self-supporting wire on intermediate supports at angles of 60 and 90 degrees (depending on the model). A special adjustable clamp is used to fix the wire. The connection is fully movable, which allows the fastener to be moved in different directions.

Anchor clamp for self-supporting system (ZAN-4)

The part is made of hot-dipped galvanized steel, as well as an external material that can withstand UV rays and precipitation. It is impossible to imagine a single structure without it, since it plays an important role in fixing the conductors.

Bracket for fastening anchor clamps (KA)

The product is a monoblock made of durable aluminum alloy. Fixation is carried out using two bolts, the diameter of which is 14 and 16 mm. The configuration of the bracket makes it easy to move around the support.

Insulated tips made of aluminum and copper (NIAM)

This element is designed for tight termination to prevent the negative effects of gusts of wind or weather. The tubular part is made of aluminum. The blade, where the fixing hole is present, is made of special copper. The insulating part is made of polymer, which is highly resistant to sunlight.

Fasteners

This category includes:

• Mounting hooks;
• Bolt hooks;
• Stainless steel fastening tape;
• Braces;
• Bugels;
• Screeds.

Without the described elements, it is impossible to carry out any installation work. But even with the materials available, it is important to act in accordance with the instructions in order to avoid unforeseen circumstances and get the work done for decades to come. It is also important to remember that installation operations are carried out with high voltages and it is forbidden to ignore safety precautions.
