JHH-2T mine intrinsically safe circuit junction box (signal connector)

JHH-2T mine intrinsically safe circuit junction box (signal connector) Jinan, China Coal Mining Equipment Co., Ltd. is a professional manufacturer, good product quality, service and good attitude, delivery speed, you are welcome to establish long-term partnership . Supply JHH (original model KLH12) mine intrinsically safe circuit with a junction box designed for JHH-2T.3T.4T mine intrinsically safe circuit junction box circuit junction box for mine I. Introduction JHH (original model KLH12) intrinsically safe mine The main circuit with a junction box for use in hazardous gas or coal dust explosion containing coal mine, coal mine is intrinsically safe wiring devices for coal mine safety monitoring system of the two-wire and four-core line of two-way to four-way cable connection , sub-line use. The material is plastic (ABS) in filling flame retardant, antistatic agents, surface insulation. Contact resistance: <0.5Ω, type of protection: Exib I JHH-3 type 3 through intrinsically safe circuit with a junction box, the Department of ABS plastic material, light weight, high strength, no rust, the contact reliability. II. The scope of products: JHH-2T mine intrinsically safe circuit junction box (signal connector) for intrinsically safe circuits in coal mine roadway, mining face, power house and other places of transit. III. Features: 1, high strength box system made of gray cast iron. 2, all the line devices are sealed, wiring reliable, easy to slip-off wire and cable. 3, junction boxes can be placed floor can also be linked to put fixed in the roadway, when used with the supplied special tool to unscrew the screws, you can remove the cover, fitted around the connecting shaft wiring devices, cable can flare introduction of terminal blocks terminal block, the whole structure design, high strength, good sealing performance, installation, easy access for underground work in harsh environments. Fourth, the technical parameters Model Rated current Rated voltage VDC ADC cable through the largest number of T cable outer diameter φmm Dimensions mm JHH-2T ≤1 ≤60 2 φ7-φ15 81 * 81 * 41 JHH-3T ≤1 ≤60 3 φ7- φ15 111 * 111 * 41 JHH-4T ≤1 ≤60 4 φ7-φ15 111 * 111 * 41 resistance of less than 1 × 106Ω, explosion-proof type: Exib I plus JHH-5, JHH-6, JHH-7 and the like. 7 through the above to be customized. Five. Instructions 1, based on the number of cable diameter select the appropriate junction box. 2, the junction box can be placed floor, can also be linked to put and fixed in the roadway. 3, first unscrew the compression nut during installation, you can remove the cover. 4, wiring first introduction means unscrew the compression nut or clamping jaws, remove gaskets, seals, and set in place the appropriate cable diameter of the cable penetration in the lead means. 5. Strip the cable and connector according to the position of the wire cable access points tied wisp. 6. The connection between the requirements of the cable are access terminals. 7. After connecting, tighten the compression nut and the clamping jaws. 8, close the cover, note pad good seal tighten the nut. ★ WARNING: wiring connector should operate in case of power failure. Note that the seat cover and seal the bell after wiring is completed.
