JHH10-6 mine intrinsically safe communications junction box Overview JHH10-6-type ore with intrinsically safe circuits are intrinsically safe fixed cable junction box multi-pass junction box production line under Q/HX003-2007 standard. Intrinsically safe circuit wiring cables and wires and sub-line device, mainly used in environments containing explosive mixtures of methane and coal dust and Ⅱ B class. It has a dust-proof, moisture-proof, compact structure, solid wiring, wire and cable is not easy to slip-off, etc.. The import and export of junction boxes and cable management, coverage width five rows of terminals. Junction box 6 different size inlet and outlet bell, suitable in HUYV series mine with communication cables and PUYV series of mine with sub signal cable wiring, only used in communication systems intrinsically safe explosion-proof Certificate of Conformity with in intrinsically safe circuit cables extend or shorten or sub-line. JHH10-6 Mine intrinsically safe communications junction box models meaning Explosionproof Type: Mine intrinsically safe. Ex-mark: Exib Ⅰ. JHH10-6 Mine intrinsically safe communications junction box Product Image JHH10-6 mine junction box technology with intrinsically safe communications parameters 1 Main technical indicators: (1) Rated voltage 60V (2) Rated current 3A connect the electric wires 10 . 3, the environmental conditions: (1) Ambient temperature -10 ° C - +40 ° C; (2) the relative temperature: ≤ 95% (+25 ℃ pm); (3) applies to no intense vibration, shock, splash, coal dust and gas explosion dangerous places. JHH10-6 mine intrinsically safe communications junction box structure characteristics: 1 box system of high strength gray cast iron made. 2, all into the line device is well sealed, solid wiring, wire and cable dial is not easy to take off. 3, JHH10-6 type 1 rows of terminals, wiring terminal block generic performance box in vitro and in vivo are equipped with ground screw. 4, the junction box can be landing placed, may also be linked to the discharge, is fixed to the roadway, in use, supporting a special tool unscrew the screws to remove the cover, around the connection shaft equipped with a junction device, cable through the bellmouth the introduction of the terminal to terminal block, reasonable design of the entire structure, high strength, good sealing performance, installed then apply to work underground in the harsh environment. JHH10-6 mine intrinsically safe communications junction box 1, according to the logarithm of the use of cable diameter select the appropriate junction box. 2, junction box floor placed, it can hang put, fixed on the roadway. Installation unscrew the compression nut, you can remove the cover. Wiring first unscrew the introduction of the device compression nut or pressed plywood, remove the washers, seals, and sets in the appropriate location of the corresponding cable diameter, the cables through the lead device. Strip the cable, and in accordance with the connection position of the core wire of the cable access points tied into a small handful. 6, according to the requirements of connected relationship, cable access to the terminal block. 7 After connecting, tighten the compression nut and compression splint. 8, cover to cover, note pad good seal tighten the nut. WARNING: The connector wiring operation should be carried out in case of power failure. Wiring should be noted that after the completion of the lid and the seat and bell seal.
