High Voltage Overview
TRIDELTA offers a broad portfolio on surge arresters for the application on high voltage up to 800 kV:
-
the reliable SB series with porcelain housing and
-
with the series SBK, SBKC and SBKT three designs with silicone housing
All TRIDELTA designs contain an excellent sealing system, which prevent the entry of any moisture and ensure decades of reliability and free of maintencance operation. The broad sorts of TRIDELTA surge arresters offer optimal overvoltage protection for different demand and application areas like:
-
highest mechanical requirement for regions with high seismic activity or for the use of arrester as supporter
-
very proper artificial pollution characteristics for desert- and coast regions and areas with high air pollution
Besides the reliable SB arresters with porcelain housing TRIDELTA offers three arrester designs with silicone housing. All the three types use high quality LSR-silicone, which has a long life hydrophobicity and UV resistance and ensures excellent artificial pollution characteristics. In comparison to porcelain arresters, silicone arresters have less weight, which enable an easy transportation, minimize the danger of damages during the transportation and assembling stage and allows all variants of installation like e.g. the application as transmission line arresters.
The difference between the three TRIDELTA arrester designs with silicon housing SBK, SBKC and SBKT lies in their design and setup, which are described in the following overview:
Porcelain
Surge arresters in top quality porcelain housings up to 800 kV, with outstanding sealing design for longest service life, available in 3 construction designs
Metaloxide varistors with high energy absorption capability and an excellent sealing system ensure a long service life. Depending on the mechanical requirements our SB arresters are available in 3 design types/sizes:
-
size 0 – max. service load 10 kNm
-
size I – max. service load 23 kNm
-
size II – max. service load 35 kNm

Silicone - Solid Core Design
Surge arresters with silicone housing up to 170 kV, economic and very low weight, very convenient for application as station or transmission line surge arresters
Our arresters with silicone housing in Solid Core Design of the SBK series are available for up to 170 kV.
As for all our arresters with silicone housing we use high quality LSR Silicone, which keeps its hydrophobic and UV-resistant/non ageing properties over the complete service life and ensures excellent artificial pollution performance.
Because of their modular design our SBK arresters in Solid Core Design can be easily manufactured adapting to variable lengths, creepage distances and clearances in accordance with customer requirements. Due to their very low weight they are an ideal solution for application as transmission line arresters in addition to their use as station arresters.
