We will present the performance, safe operation methods, and technical parameters of JP outdoor integrated distribution box (compensation\controlerminal\lighting)
Product Overview:
JP series outdoor low-voltage integrated distribution box is a new type of integrated control box integrating power distribution, metering, protection, control and reactive power compensation, which is designed according to the requirements of power grid construction and transformation and power grid operation experience, in line with the principles of safety, economy, reasonableness and reliability, and can be added to the leakage protection function according to user requirements. The product has the advantages of novel structure, reasonable, high protection level, convenient installation and commissioning, maintenance and overhaul. It is an ideal terminal low-voltage complete set of equipment in the current power grid transformation.
1. Scope of application
JP series outdoor integrated distribution box, is a set of metering, outlet, reactive power compensation and other multi-functions in one to achieve outdoor comprehensive power distribution device, with short circuit, overload, overvoltage, leakage protection and other functions, small size, beautiful appearance, economical and practical, installed on the electric pole of the transformer on the outdoor pole, is a new generation of ideal power distribution products for the transformation of urban and rural power grids.
