PURPOSE
The Network Distribution Cabinet is intended for power distribution and is most commonly installed in a cable network for the purpose of disconnecting from the main power cable.
ENCLOSURE
The enclosure of the cabinet, same as the base, is made of insulating material, high-quality pressed poliester reinforced with glass fibers, resistant to mechanical, thermal and UV influences. There is a possibility of mounting the cabinet enclosure on the concrete foundation.
INSTALLATION
It is intended for exterior mounting in cable tile on a layer of thin concrete or fixed with base bolts if there is no stabilization plate.
EXECUTION
It is made of a pressed polyester enclosure of 320 mm depth on a polyester or concrete base. The standard height is 864 mm and the size of the casing 00, 0, 1 and 2.
