Series Mining General Low-voltage Switch Cabinet

Product Introduction

General-purpose low-voltage switch cabinet for mining GKD: The main performance of the product: rated voltage U40V/690V/400V, rated current below 2500A, protection level IP43.The products comply with GB/T12173-2008 "General Electrical Equipment for Mining" and GB/T7251.12-2013 "Low-voltage switchgear and Control Equipment". The switch cabinet adopts a modular general cabinet structure, and the frame adopts 8MF cold-formed steel. The parts of the general cabinet are designed according to modularity, with a high general coefficient, flexible installation of components, and reasonable cabinet structure design, which is conducive to the heat dissipation of components and improves the thermal stability of the cabinet. The size of the cabinet considers factors such as mine transportation, installation, small footprint, and easy maintenance. Applicability and economy All very good.The main configuration of the product: The cabinet is mainly composed of isolation switches, circuit breakers, contactors, transformers, instruments, etc., and can also be equipped with leakage monitoring devices, automatic fire extinguishing devices, automatic dehumidification devices, etc. according to user needs.
