JHH-6 (20 pairs) mine with intrinsically safe junction box Overview JHH-6 (20) mining intrinsically safe wiring box of the original model: JHH-1/60-20S internal mounted terminal block 10 pairs 20 pairs of the product according to Q/KH003-2010 standard production. This product can be used with the coal mine communications, monitoring system cables supporting, can be used in coal mine working face, roadway cavern on down the mountain, such as gas and coal dust dangerous environment, as cable and intrinsically safe communications, surveillance systems equipment connecting means. Two, JHH-6 (20 pairs) mine explosion-proof type of intrinsically safe junction box Ex-mark: Mine intrinsically safe. Ex-mark: Exib Ⅰ. , JHH-6 (20 pairs) mining intrinsically safe junction box use of the environment a Ambient temperature -10 ° C - +40 ° C;, the relative temperature: ≤ 95% (+25 ℃ when); c atmospheric pressure: 86-106KPa; d environment sexual gas and coal dust and other explosive substances; e, the environment should be free of corrosive gas; 4 JHH-6 (20 pairs) mining intrinsically safe junction box technology requirements Rated voltage 60V rated current 3A contact resistance of less than 0.01 ohm insulation resistance greater than the of 500 megohms surface insulation resistance of less than 1 × 109Ω five JHH-6 (20 pairs) mining intrinsically safe junction box for use (1) This product consists of four groups The mutually parallel terminals composition. Three pairs in each line, a total of 12 pairs. (2) This product can only be used for the operating voltage of 60 volts DC, intrinsically safe circuit working voltage 3A. (3) the product of the seals, the inner diameter of the flat washer, according to cable diameter chosen at random in the installation. (4) The installation must tighten the line nut fastening screws, to ensure reliable sealing. JHH-6 (20 pairs) Mine Use intrinsically safe junction box (1) This product can be used for communication intrinsically safe 60 volts, monitoring equipment, without proof review authority to confirm, can not be turned on simultaneously two Road intrinsically safe power supply. (2) The connector can be used to comply with the above conditions in the mine area, including the mining face. WARNING: The connector wiring operation should be carried out in case of power failure. Wiring should be noted that after the completion of the sealing of the lid and seat. Seven, JHH-6 (20 pairs) mine intrinsically safe junction box Order Information: Order of the contract based on the product name, the number, mailing address, zip code, station Tel write clearly and associates.
