Introducing Our Unbeatable 4S Technology

Our 4S installation technology of Stepless Shearing Screw & Silicone provides a complete product range with fewer connectors. The 4S Technology is a combination of stepless shearing screw with liquid silicone. This offers an unbeatable solution for more reliable, easy and fast installation. 

As silicone insulation is elastic, it enhances durability and environmental resistance. The stepless shearing screw always cuts off at the right spot and guarantees the connection consistency. Moreover, this means a fast and easy installation leading to a unified result – every time. 

With the complete, wide product range of broad application possibilities, installers need fewer connector types for less product variations, which simplifies inventory, saves time and reduces costs.

  • High-voltage and impulse​
  • PD measurements​
  • Heat cycle aging​
  • Short-circuit​
  • Climate​
  • Corrosion​
  • VLF voltage tests​

Saving Costs Through Less Product Variations

Now that the screened separable connector family is complete with new products that have larger cable cross-sections and higher voltage levels, there is no longer a need to buy multiple various products. Hence, the application possibilities are broad, which in turn ensures less product variation and offers cost savings. 

Our separable connectors are suitable for connecting medium voltage cables to transformers, motors and particularly gas insulated switchgear in both indoor and outdoor settings​. The products offer tested security especially for renewable energy grids and primary substation internal cabling.

Short Lead Times, Reliable Delivery

All the core components in our separable connectors are manufactured and managed in-house to ensure quality and dependable delivery. The cable lugs are produced in Porvoo, Finland, the silicone molding and assembly take place in Keila, Estonia, and the surge arrester cores are made in Bagnères-de-Bigorre, France. Our lead times are short, and the integrated European production model ensures that every product meets Ensto’s standards for performance and reliability in the most demanding conditions.
