High voltage insulators

High voltage insulators:
Surge arresters 11 kV – 420 kV:
Orient is a supplier of a wide range of surge arresters from Tridelta, Germany
The surge arresters are of composite material, is delivered according to all requirements and are tested according to IEC 60099.
The surge arresters are designed for outdoor equipment like transformers, cables, generators and all electrical components exposed for atmospheric over-voltages.

Composit Support insulators 24 kV – 145 kV:
The insulators can be supplied in all above mentioned currents with a variety of end fittings and strengths to fit with different national standards.
The insulators are used on disconnectors and as general support insulators.
The products are tested according to IEC 61109.
We also supply support- and suspension insulators from 52 kV to 145 kV.

Porcelain Support insulators 52 kV – 420 kV:
The insulators can be supplied in all above mentioned currents with a variety of end fittings and strengths to fit with different national standards.
The insulators are used on disconnectors and as general support insulators.
The products are tested according to IEC 60168-2001.

High voltage lines 52 kV – 145 kV:
Orient is a supplier of a wide range of masts, pillars, supports and towers to the utilities and railway.
We also supply line material support insulators, line, suspension equipment and OPGW.
During the design/construction phase, and when calculating strength.

Circuit breakers 72.5 kV - 420 kV / 3150 A (4000 A):
Orient delivers circuit breakers, and co-operates with Orient.
Orient Instrument Transformer has production in Zagreb, Croatia and has a wide product range of circuit breakers.
The products are of high quality standard and are competitive on price and delivery time.
