High voltage distribution transformers anti-theft metering box protective cover _ _ trailer coupling guard

High-pressure metering box tamper with variable protective box inside the box with original self-locking structure, cover plastic material imported environmentally friendly flame retardant polycarbonate, the base for the imported fire-retardant ABS. Cover and base with convex structure, a linear outlet to protect me from the outlet hole leads, aperture meet 35-240 mm wire leads, leads straight to avoid external metal objects into cheating. Second line leads from the cable to the meter box or the measuring chamber. Blockade padlock and stringing Sealing lead. With matching table box optional three-phase and three-phase two a epitope epitope box. Installation steps: First, the base covering low-voltage distribution transformer terminals, fasteners through the horizontal screw lock any two voltage insulator and tighten the screws with a longitudinal chassis, and then install CT, access to secondary cables, tighten the secondary Cable pore pressure line cards. Respectively penetration from outside to inside a lead wire directly into the hole, and after wearing low-voltage distribution transformer access around the CT terminal, after checking the wiring is correct, close the lid, and then blocked the pass-box with a padlock and seal lead. Scope: No. protective box utility to 80KVA-315KVA transformers, large protective case practical in 400KVA-630KVA transformers.
