Cable Sleeves

Rubber Cable Sleeves


SES Sterling HELAVIA and SILAVIA sleeves support and insulate the ends of electric cables. They can also be used as markers and thus provide a double functionality.


Cable sleeves support and insulate the ends of electric cables. Rubber sleeves help protecting from dirt deposits, corrosion and abrasion.


SES Sterling sleeves can be used as protectors and are very ergonomic. SES Sterling offers different types of standard sleeves:

  • HELAVIA sleeves in polychloroprene rubber (black and coloured)

  • HELAVIA sleeves in special lengths in polychloroprene rubber (black)

  • SILAVIA sleeves in silicone rubber for high temperatures (natural, transparent and coloured)

Additionally, we offer tools for easy installation of sleeves (sleeve expanders) and application aids to help you use our sleeves efficiently.

Insulating Sleeving and Sleeves


Insulating sleeving is used for the protection and the insulation of electric cables. It is available in different colours with dielectric strength from 20 to 35kV/mm and 3 materials:

  • PVC: this material is available in different colours, has a good resistance to light and is used for the marking of cables. Resistant to ozone, ageing and acids, the PVC sleeving is specially used for the isolation of electric cables, mechanical protection and the transport of fluids with low pressure at room temperature (except special aggressive products).

  • TPE: this material looks like rubber and is used for applications that need a good resistance to high and low temperatures. Furthermore. It offers more elasticity and flexibility than PVC.

  • Silicone: specially used for electrical insulation, this halogen free material has a good resistance to high temperatures. All the sleeving are available in sleeves upon request.


Available types:

  • PLIO-SUPER: PVC for general use

  • PLIO-SUPER bicolour: PVC for general use

  • PLIO HT LF: PVC for high temperatures

  • PLIO BT LF: PVC for low temperatures

  • PLIO THICK WALLED: Extra efficiency

  • PLIO INDUSTRIAL: PVC in long lengths and flexible applications

  • PLIOPRENE TPE: TPE halogen free

  • SILA-SUPER: Silicone halogen free

SES Sterling Heat-shrinkable slevees

Heat Shrinkable Sleeves


Nexum offers heat shrinkable tubings from Brady an SES Sterling. Brady focuses on DIY marking with shrinkable sleeves and SES Sterling for general installation and maintenance purpose shrinkable sleeving, but can also offer ready-made marking sleeves.

SES Sterling was the first company in Europe producing heat shrinkable thermoplastic sleeving. Choice of materials depends upon physical properties, economics and aesthetics. The company manufactures two types of heat shrinkable sleeving:

  • The PLIO-R heat shrinkable insulating sleeving is economic. It is a thermoplastic material that can be sealed. Dielectric properties, ageing and weather resistance are excellent. Heat shrinkable sleeving PLIO "R" is delivered inflated and sealed at both ends so that it cannot shrink while being transported or stored. Storage temperature: Max. 18°C.

  • Heat shrinkable tubing PLIOFINE is composed of cross-linked Polyolefin (derivative from polyethylene), unlike heat shrinkable sleeving PLIO "R" it cannot be melted or welded and has excellent chemical properties. It is cost effective. Dielectric properties, ageing and weather resistance are excellent, and the sleeving needs no special storing conditions as it remains inert up to +50°C.


Brady offers DIY sleeves for cable and general installations marking. We can provide handheld and desktop industrial printers and a large variety of materials with different physical properties and also multiple colours.

Braided Sleeves


Nexum offers a large variety of braided sleeves from different suppliers: SES Sterling, Flexicon, Interflex and Agro. Expandable braided sleeving in plastic or metal versions is the ideal solution for supporting and protecting cable harnesses and many other types of flexible installations. It also adds to the physical appearance of the end product.

Main types of braided sleeves:

  • Plastic (PET, PA6.6, PBT) sleeves in black or grey colour, standard or halogen-free

  • Insulating Non-expandable braided sleeves with PUR or silicone coating that can also serve as high-temperature protection up to 290°C

  • Metal (stainless steel, galvanised steel or tinned copper) braided sleeves, used mostly for EMC shielding and high-temperature and abrasion protection

  • PET filaments coated tinned copper intended for EMI shielding, protects connections sensitive to electromagnetic disturbances. Its copper coated PET filaments give greater lightness and flexibility than current metal braided sleeving and can also be cut with scissors.
