SWITCHGEAR MODIFICATIONS PROTECTION RELAYS

Our design team is constantly designing new equipment which incorporates the latest 3.3 to 36 KV VCB, SF6 & Air Circuit Breaker technology to replace either worn out or dangerous circuit breakers, in particular the range of ‘Manually Dependent’ oil circuit breakers manufactured before 1970 and still in use in vast numbers within the countries manufacturing industry.

We have achieved, in the majority of cases, the provision of a self-contained cubicle that replaces just the circuit breaker itself and mounted on the existing framework utilizes the original power connections without the need for any alterations to the fixed portion of the switchboard.

The obvious advantages to this way of updating our switchgear are no need for lengthy shutdown periods (in some cases the conversion can be done without any shutdown of circuits other than the ones being changed); can be done over a period of time to spread the initial costs; no need to disturb power cables, etc.

With over 12 years of experience in retrofitting obsolete switchgear, we have developed an impressive range of support for the following manufacturers: Schneider Electric – Merlin Gerin – ABB – GEC – Siemens – CG – Toshiba Our support for obsolete switchgear is forever increasing. If your switchgear is obsolete and is not specified by the manufacturers above, we would be more than willing to discuss how we can provide the best solution in upgrading your switchgear.
