Explosion distribution box is divided into: explosion-proof lighting box, explosion-proof power boxes, explosion-proof control box cabinet offer, proof control cabinets, explosion-proof electrical cabinet stainless steel cabinet, explosion-proof control box, explosion-proof boxes, explosion-proof starter box, explosion motor starters, soft starters proof, explosion-proof inverter box, explosion star delta starter box, explosion-proof auto-voltage starting box, explosion-proof magnetic starter box, explosion-proof electrical outlet boxes, portable explosion-proof box, BMG Distribution explosion distribution box 7 Selection into the outlet box low voltage cable factory explosion-proof cabinet, select the cable should meet the technical requirements. For example 30kVA, 50kVA transformer distribution box into the line using VV22-35 × 4 cable splitter outlet using the same specifications VLV22-35 × 4 cable; 80kVA, 100kVA transformer, distribution box into the line were using VV22-50 × 4, VV22-70 × 4 cable outlet splitter were using VLV22-50 × 4, VLV22-70 × 4 cable, the cable crimping copper and aluminum lugs and then bolted connection with the distribution box trailer coupling . 8 fuses (RT, NT type) selection. The total distribution transformer low-voltage side overcurrent protection fuse rated current, should be greater than the low-pressure side of the distribution transformer rated current, and generally 1.5 times the rated current proof cabinet, melt the rated current transformer should be allowed too load multiple and fuse characteristics are determined. Outlet circuit overcurrent protection fuse melt rated current and should not be greater than the total current protection fuse rated current, rated by melt loop normal maximum load current selection, and should escape the normal peak current-proof electrical control cabinet price | 20 years Koretoyo Explosion | Pingdingshan explosion-proof cabinet Koretoyo by Zhejiang Electric Co., Ltd.
