ACB Servicing and Retrofitting Solutions

We are certified ABB service centre for servicing of low voltage switchgears. Our ACB repair services are fast and effective, helping you restore your operations quickly. ABB certified service engineers can provide both on-site repair and workshop repair services, supported by our extensive stock of genuine ABB parts. ACBs are the cause most of power distribution system failures, mainly due to lack of maintenance, dust, hardened grease, corrosion and/or frozen parts that prevent the proper operation of the trip linkage Maintenance is the preferred choice to ensure reliable operation and extend the life expectancy.

As with all electro-mechanical devices, major electrical equipment manufacturers recommend maintenance of air circuit breakers to ensure proper operation and to maintain equipment warranties. With regular service air circuit breakers can remain in service almost indefinitely as long as spare parts are readily available.

ACB Retrofitting Solutions

We are authorized channel partners of ABB for providing ACB retrofitting solutions. With SACE Emax 2 retrofitting kits, ABB Low Voltage Breakers extends the product offering and gives customers the opportunity to immediately take advantage of the benefits of the Emax 2 circuit-breakers. Substituting Emax 2 in switchgear allows an upgrade in performance and capabilities, as well as an increase in the Life Cycle and safety of the circuit-breaker.

Retrofitting a new low voltage circuit breaker also offers many advantages over their older counterparts. Key benefits are increased lifetime, improved reliability, and options for enhances maintenance diagnostics and communication.

OLTC Servicing and Testing

We are authorized service provider of OLG (On Load Gears) for OLTC servicing. A comprehensive, unmatched network of service engineers guarantees 24/7 availability with fast delivery of genuine spare parts. OLTC is a vital part of the transformer and is used for correcting the transformer secondary voltage by changing tapping position. There are large numbers of mechanical & electrical components which are subjected to stringent mechanical & electrical stresses. Every tap change operation results in to arcing between the contacts & thus carbonizing the tap-changer oil & erosion of contact. It is therefore necessary to maintain the OLTC on periodical basis to ensure uninterrupted trouble-free service.
