To achieve uninterrupted electricity supply, you should ensure a reliable connection of all wires. Usually, the method of twist is used to solve such purposes, but it is not always reliable. All wires that are connected in a similar way are prone to overheating and oxidation. To avoid similar problems, use copper sleeves.
Copper lugus sleeve
In this article, we reviewed all the features of copper sleeves that were a mezzani. These attributes are perfectly suitable for connecting wires.
What is GML
Copper sleeves are referred to as GM. GML is a copper sleeve, which is undergoing a mezzani procedure. After the manufacture, a special tin-bismuth layer is applied to it. This is especially necessary for products that are made of copper, as they can be overlooked.
GML is presented in a wide range
Special coating ensures reliable protection against corrosion formation. However, it is necessary to remember that it is prohibited to use similar products with aluminum wires. This is due to the fact that when compressed, the protective coating can be collapsed and the GML sleeve will enter into a chemical reaction with aluminum.
Main types of sleeves
Connecting sleeves can have the following varieties:- Ha. This designation suggests that the manufacture of the sleeve occurred from aluminum. This type can only be used to connect aluminum wires.
- Gam. This is a combined type that is popular. Products can be used for butt compounds of aluminum and copper wires.
- GS Connecting sleeves represent the tinned products to which polyvinyl chloride isolation will be applied. The crimping occurs with special ticks directly through the coating.
To ensure a connection in control and measuring instruments or electrical panels, you can use tubes for connecting power cables. Cable sleeves will be highly resistant to deformation and will be able to protect the wire from various mechanical damage.

Varieties of cable sleeves
Depending on the installation method, the sleeve can be divided into the following categories:
- for soldering;
- For crimping;
- For connecting bolts.
Each separate type can have their own features with which you need to get acquainted in advance.
Select section
Dimensions and section can be diverse. The minimum section today is 1.5 square meters. mm. Copper tinned sleeves in a section should fully comply with the wire. The design of the sleeves can also be diverse. Depending on the design, the following varieties can be distinguished:
- Through. The design of this sleeve is the most simple and presents the usual tube.
- GML with partition in the middle. This type can be used for the join connection.
Gils cross section
The elongated wires can be connected using special tubes that are equipped with partitions. The principle of compression of the sleeve is quite simple. To do this, it is enough just to use the press with ticks for crimping the sleeves. To ensure reliability, squeeze the sleeve is better in several places. After performing these stages, it is possible to be insulated with a shrink tube.
Stages of crimping
To perform crimping with the help of sleeves, you need to follow the following steps:- First of all, decide which type of sleeves you are planning to use. Wire material must fully fit the material of the sleeve. Copper connectors use for cables that are made of aluminum is not recommended, as chemical interaction can occur.
- The inside of the sleeve must be treated with quartz-vaseline pastes.
- Now it's time to prepare the veins of the connected wires. At this stage, it is necessary to remove insulation from the wires.
- After removing the insulation, the veins need to be cleaned. At the end of this stage, the wire surface must purchase a metal shine.
- Put on the prepared wires connective sleeves. When performing this work, it is necessary to ensure that the ends of the connected wires docked each other in the center of the sleeve.
- Perform a special tool pressure. The action must be performed until the matrices are completely coming.
- Inseulate the location of the connection. To do this, you can use the tape or heat shrink tube. To pour the tube to use a construction hairdryer.

These are the main stages that need to be performed for the organization of high-quality crimping. Technology can be used to connect wires with a large cross section or for wires in a high load line.
Common Errors in Pressing
Quite often the masters have no special tools for crimping. In this case, you can use pliers. However, it is not recommended to do this, since there are special matrices on the ticks.
Pliers for crimping sleeves
In the absence of a copper connecting sleeve, a conventional tube can be used. The free space between and the wall of the copper tube can be filled with the help of pieces of others lived. If you bought a GML with an inappropriate cross section then some consumers cut part of the conductor.
If it was chosen too large GML then when connecting the multi-voltage wires, they can not be folded and twisted into the sleeve. To connect the wires using the sleeve, you do not need to use a soldering iron or welding machine.
