Cold-Shrink Technology Medium Voltage Cable Joints

BC Cellpack Expands Its Portfolio with Cold-Shrink Solutions for Medium Voltage – Now Available in Bulgaria 

BBC Cellpack Electrical Products has expanded its product portfolio with a new series of Cold-Shrink joints for medium voltage (CCMSV), designed for connecting and insulating single-core cables in networks up to 36 kV. 
The new kits are now available to Bulgarian customers through Cellpack’s official distribution partner- Contragent 35 Ltd. 

 

Reliable Technology – No Heat Required 

The Cold-Shrink products are made from high-quality liquid silicone rubber (LSR) that automatically shrinks around the cable during installation. 
This ensures a constant radial pressure and uniform sealing, without the need for heat, gas torches, or special tools. 

Key advantages for Bulgarian installers and field technicians include: 

• faster and safer installation on site 

• no risk of thermal damage 

• minimal network downtime during repair work 

• enhanced reliability of electrical connections 

 

Certified European Quality 

The BBC Cellpack Cold-Shrink joints have been tested according to CENELEC HD 629.1 S3:2019, ensuring: 

• reliable insulation and electric field control 

• high resistance to moisture, UV radiation, and ageing 

• long service life, even under harsh environmental conditions 

These features make the products an excellent choice for Bulgarian energy utilities, as well as for companies involved in electrical installation and cable jointing for medium-voltage networks. 

 

Flexible Application 

The Cold-Shrink range is compatible with: 

• single-core polymeric insulated cables (XLPE, EPR, HEPR) 

• aluminium and copper conductors of various cross-sections 

• different cable screen designs (copper tape or wire screen) 

Each kit includes mechanical screw connectors with pre-set torque, ensuring fast and secure connections without the need for crimping. 
Additional sealants and the silicone outer layer provide complete protection against moisture and dust, making the system ideal for both outdoor and underground cable installations. 

 

Benefits for the Bulgarian Market 

• optimized solution for new installations and maintenance 

• lower installation and maintenance costs 

• improved on-site safety 

• extended service life of cable connections 

 

With the new Cold-Shrink CCMSV series, BBC Cellpack brings to the Bulgarian market a practical, safe, and certified solution for medium-voltage applications. 
This technology combines German manufacturing quality with the efficiency and convenience required by modern Bulgarian installers and network operators in their daily work.
