EHV Cable Outdoor Termination
The development of high voltage XLPE system goes back to the 1960’s since then production and material technology have improved significantly providing reliable maintenance free products to utility industry. The different version of the terminations are designed for operation under severe outdoor conditions and operation voltage up to 550 KV. The terminations can also be used indoor where appropriate space is provided.

Outdoor termination with porcelain insulator (1a):
This termination type covers the full range from 72.5 KV to 420 KV. It is used for gas pressure cable, oil filled cable and for XLPE cable. It is in use for many years and has the longest and satisfactory service history. The insulator may be in brown or grey colour protective spark gaps are as an option.

Outdoor termination with composite insulator (1b):
This termination type is for XLPE cable. The basic design is identical with that of the porcelain termination. The composite insulator, however, is of much lower weight. This is advantageous with respect to lifting equipment needed for installation and also for supporting constructions.
Dry type outdoor termination (1c):
The dry type termination for XLPE cable is completely free from any liquid or gaseous filling medium. Apart from the environmental aspect, the dry design provides further advantages like easier installation and no need for filling equipment, both contributing to significant savings for installation of the terminations.
