DFW-12 / 630A high-voltage cable branch box Continental

Introduction: DFW-12 / 630A high-voltage cable branch box Continental is the most widely used in power in recent years in the cable distribution network systems engineering equipment. Its main feature is a two-way door, the use of insulated wall bushing as the connection busbar, with a small length, cable clearly arranged, three-core cable without large span crossing and other significant advantages. Generally the rated current of 630A bolted connection cable connector, a variety of different user requirements can provide a satisfactory technical solution. Uses: Widely used in: urban industrial parks, urban residential areas, urban commercial centers, mines and steel mills, automobile, petroleum, chemical, cement and other large-scale industry and on other occasions Bowling 10KV cable distribution network system connecting ring distribution network It is ideal equipment network reform. Features: The performance parameters fully insulated, sealed, full protection, all operating conditions; inlet and outlet for flexible, practical application up to 8 branches into the outlet; flood water, anti-dirty, anti-condensation, anti Cream, corrosion resistance; small, compact structure, easy to install, easy to operate; can take to avoid the gasifier; installable live indicator, indicating the operator live line; can install cable type fault indicator, easy to quickly find cable faults; there are a variety of housing material can choose: high-quality steel, stainless steel. Conditions: 1. Altitude ≤1000m; (If you have special requirements can be specified when ordering) 2. Ambient temperature: a 25 ℃ ~ + 40 ℃; 3. day average relative humidity of not more than 95%; monthly relative humidity average does not exceed 90%; 4. Seismic capacity: 8 degrees; 5. No severe vibration and shock as well as fire, chemical corrosion, explosive atmosphere, DFW-12 Normal 10KV cable branch box, DFW-12 Normal 10KV branch cable boxes main technical parameters: Table 1: Project Parameters Project parameters Rated voltage 12kv junction resistance <40μΩ rated current of 630A partial discharge <10 / kv rated frequency 50Hz and wet experiments 1kv / 100h through rated thermal current 20kA / S Applicable cable type XLPE rated dynamic current (peak) 50KA suitable cable cross section 25-400mm2 frequency withstand voltage 45kV / min Ambient temperature -40 ℃ --- 55 ℃ lightning impulse withstand voltage 105kv applicable Altitude <3000m Table II: Model Specification No. LBH 1 DFW-12-2 two branches (one into a) 800 710 1020 2 DFW-12-3 three branches (one into two) 800 710 1020 3 DFW-12-3A four branches (one into three) (a into two) 920 710 1020 4 DFW-12-4 four branches (one into three) (binary two) 920 710 1020 5 DFW-12-4A five branches (one into thinking a) (binary three) 1040 710 1020 6 DFW-12-5 five branches (one into thinking a) (binary three) 1040 710 1020 7 DFW-12-5A six branches (one into five) (binary four) 115071010208 DFW-12-6 six branches (one into five) (binary four) 1150 710 1020 9 DFW-12-6A seven branches (one into six) (binary five) 1390 710 1020 10 DFW-12- 7 seven branches (one into six) (binary five) 1390 710 1020 11 DFW-12-7 eight branches (one into seven) (binary six) 15,007,101,020 Note: 1, "A" represents the branch inside an arrester 2, size 3 according to user needs, the cabinet has made of stainless steel or high quality steel
