We offer an array of MV (Medium Voltage) switchgears that suit all medium voltage applications. The main task of medium-voltage switchgear is cost-efficiency, safe & reliable power distribution. And, this is a responsibility we accept. Our array of MV switchgears caters to a wide range of medium voltage applications such as utility substations, power plants, cement plants, metal plants, solar applications, wind farm projects etc.By taking an innovative approach, our products offer tangible advantages such as lower capital expenditure, longer life cycle, lower life cycle cost and a reduced environmental impact. Along with our LV (Low Voltage) switchgears & other range of products, we enable the realisation of smart grids thus laying the foundation for smarter energy efficient buildings, infrastructure and for greener cities. Our range of MV switchgears includes Indoor Draw out Fixed type, Outdoor type Porcelain Clad Vaccum Circuit Breaker.

Although last in the power distribution chain, LV switchgears are the backbone in deciding the reliability of the entire distribution set-up and hence require smart designs & careful manufacturing.

Autoreclosers can be installed in branch feeder lines in a power distribution system or in a Ring Feeder arrangement for a simple Distribution Automation system. It has been observed that about 70% of faults in a power distribution system are Transient Faults typically less than 100 milli-seconds. With an Autorecloser capable of providing up to 4 reclosing operations each operation user configurable the Autorecloser can monitor the state of the fault on every close. If the fault has been transient then supply is restored. In the case of a permanent fault the Recloser will lockout and isolate the fault. This increases reliability of supply. For the Ring Feeder arrangement they can be set to isolate the faulty section and restore supply to the maximum number of users.
