We manufacture and supply Metering Cubicles upto 33KV as per DISCOM standards where metering is done in 3 phase 4 wire system employing 3 current transformers and 3 voltage transformers. Required space is provided for entry of H. T. cable from the bottom through detachable gland plates. Bus bars are epoxy encapsulated. Canopy will be provided for outdoor type metering cubicles.
General UseControlling of the incoming power supply voltage and its distribution among the other appliances
Industrial metering cubicles are used for the controlling of the incoming power supply voltage and its distribution among the other appliances in the industry in most appropriate and desirable manner. These are provided with auto sensing and intelligence technologies to make its work more efficient and reliable. The cubical are dust proof and pilfer resistant. The cubical are available in three phase three wire or three phase four wire systems. It is widely acclaimed in the industry, owing to its ease of operation, minimal maintenance and low cost.
Features:
