Cable pass, sleeves

Sleeves, conduits and seals for cables

Purpose and Applications

Sleeves are used to insulate cable wires, cable lugs and shoes, as well as connection between different cables. These components are important in maintaining the efficient and safe operation of electrical systems. Sleeves and passages serve to isolate and protect the cables from external influences and unwanted contacts, as well as stability of the cable and prevent it from breaking and twisting.

Cable sleeves are generally used to create ground connections or to insulate the ends of cables. They can be made of different materials such as heat-resistant polymers, rubber or plastic. This type of sleeve offers protection against moisture, dust and other external factors that can affect electrical connections.

Sleeves and conduits are a basic and important component used to insulate cables when passing through openings in enclosures, boxes or other structures. They prevent friction and provide additional protection against external influences such as moisture, radio frequency interference, electromagnetic fields as well as insulation and strength when connecting different types of cables.

Types of sleeves

There are different types of electrical circuit sleeves, depending on their applications and requirements.

• Heat Shrink Sleeves: These sleeves shrink when heated and are used to insulate and reinforce cable ends. They are effective in protecting against moisture and mechanical damage.
• Silicone sleeves:: Silicone sleeves are flexible and resistant to high temperatures. They are often used in high temperature environments and cable ends where flexibility is required.
• Flexible cable sleeves: These sleeves are made of a flexible material such as PVC and are suitable for protecting cables in conditions where there is frequent movement or bending.
• EMI/RFI sleeves: Insulate cables from electromagnetic or radio frequency interference. This is important in applications where signals must be protected from external influences.

Choice makes the quality of work

It is important to select suitable sleeves and seals depending on the specific requirements of the electrical system and the environment in which they will be used. They must meet safety standards and provide reliable protection of cables and electrical connections, protect the system from contamination and damage, and extend the life of the electrical installation.
