SafeRing is a SF6 insulated ring main unit for the secondary distribution network. SafeRing can be supplied in a number of different configurations suitable for most switching applications in 12/24 kV distribution networks. The RMU has a completely sealed system with a stainless steel tank containing all the live parts and switching functions. 

A sealed steel tank with constant atmospheric conditions ensures a high level of reliability as well as personnel safety and a virtually maintenance-free system. The RMU offers a choice of either a switch fuse combination or a circuit breaker with relay for protection of the transformer. SafeRing can be supplied with an integral remote control and monitoring unit.

CSS is a type tested assembly comprising an enclosure containing Medium Voltage (MV) switchgear, Distribution transformers, Low Voltage (LV) switchboards, connections and auxiliary equipment.

•

CSS is for energy transformation in secondary distribution network from MV to LV or LV to MV systems.

•

These substations are typically installed in locations accessible to the public and should ensure protection for all people according to specified service conditions

•

All CSS components shall be type and routine tested per their relevant product standards

Chirag Techno Electricals Company is one of the world’s most experienced cable suppliers with the capability and expertise to offer the full scope of supply in high voltage cable solutions, from system studies and design to manufacture, installation and commissioning. We offer High Voltage and Medium Voltage Cable kits and onsite cable jointing services.

We undertake Overhauling / servicing work for any type and make of Transformers / CSS / RMU / HT Panel up to and including 100MVA, 220KV Class. Overhauling is a scheduled preventive maintenance activity mentioned in IS 10028. Overhauling involves inspection of its parts and accessories, oil level, testing and monitoring of electrical characteristic of electrical products and its parts and accessories. Depending on the reports of inspection and tests conducted necessary servicing, rectification, replacement activities are carried out. It reduces chances of breakdown and enhances life of electrical products. We have adequate team of site engineers, supervisors, and skilled labors for providing site services for emergency servicing.
