Main Component

A composite insulator with upper metal work, metal base plate with supporting insulators and pre-moulded stress cone for electrical field control and silicone oil for electrical insulation.

Special features:

  • Integrated pre-moulded stress control systems made of rubber
  • All metal parts made of corrosion-resistant aluminium alloy
  • Top bolt available in two versions, screw type or compression type
  • Different top bolt diameters available to suit the cable dimensions

Dry outdoor termination solutions

Requires special construction measures as it is constructed for different weather exposure: In addition to much longer creepage distances, which have to withstand contamination, terminations for the outdoor area have a tinned connector bolt to prevent chemically induced corrosion.

Enabling Maintenance-Free Operations

The use of our terminations with a self-supporting function gives significant cost advantages. Installation time can be significantly reduced by using ready-made components. At the same time, the risk of undesired damage, e.g. to oil-filled terminations, such as soil pollution from leaks, or discharge in the event of internal faults, is avoided.

Some of the features and advantages:

  • Screw connection technology enables flexible and faster delivery times
  • Compared to the oil-filled standard variant, the self-supporting terminations are environmentally friendly
  • Component prefabrication in the factory drastically reduces installation time making installation easier

FEV 72-245-V

The different versions of this outdoor termination (type FEV-V) are designed for operation in a variety of outdoor conditions. The main components of the termination are a composite insulator with upper metal work, a metal base plate with supporting insulators and pre-moulded stress cone for electrical field control as well as silicone oil for electrical insulation.

Special features:

  • Integrated pre-moulded stress control system made of silicone rubber
  • All metal parts made of corrosion-resistant aluminium alloy
  • Termination is standing on supporting pedestal insulators, so that the cable screen can be isolated from earth
  • Top bolt available in two versions, screw type or compression type
  • Different top bolt diameters available to suit the cable dimensions
  • Type test certificate in accordance with IEC 60840 available
  • Cold-applied insulating fluid
