JHH Series cable junction box colliery mine explosion-proof cable junction box

JHH Series cable junction box, cheap, is your ideal device mine with a junction box. JHH Series cable junction box is mainly used in the coal mine or a variety of fiber optic cable within the cable connecting the tail, and protect the cable connectors and wiring role. Structural design of this series junction box is turned down style, open housing need to unscrew four screws fixing the base below, convenient and reliable installation. The shell uses a high quality aluminum alloy molding, high mechanical strength, and by electrostatic spray, making elegant appearance. Fiber optic disc box asylum flip design, the opening angle of up to 90 ° or more, fixed heat shrink tubing, coiled fiber, expansion, and maintenance are very convenient. JHH Series cable junction box of imported ABS flame retardant antistatic reinforced plastic, high strength, corrosion resistance, terminal structure suitable for the connection of the cable terminal room, reasonable structure, reliable sealing, easy construction. Can be divided according to the different environment of vertical and horizontal two sizes, these two specifications are respectively 12 cores, 24 cores, 48 ??cores and 144 cores over various models with different capacities. JHH Series cable junction box is buried in the ground form, so the junction box sealing is very important. If the junction box, then the water will cause the fiber surface cracks, a long time, then the fiber will break. Cable junction box sealed, mainly cable and junction box, junction box sealing between the two parts of the upper and lower cover. When the cable junction box sealed, polished first cable jacket, so you can make the cable and seal more tightly sealed better. Junction box cover seal is mainly down to use sealing tape should be uniform, and tighten the screws on it without leaving gaps. JHH Series cable junction box performance parameters: the optical properties of the cable junction box JHH series: no additional attenuation; sealing the cable junction box JHH series: the inflation pressure is 100KPa ± 5 Kpa, soaked in water for 15min no bubbles escape; JHH Series Cable stretching junction box: can withstand> 1000N axial tensile force; JHH Series cable junction box crushed: can withstand 2000N / 10cm pressure 1min; JHH Series cable junction box shock: 16N.m can withstand shocks three times; Series cable junction box JHH life:> 20 years; JHH Series cable junction box Insulation resistance: Buried 1.5m deep water for 24h, box insulation ≥2 × 10MΩ / 500V (DC); JHH Series cable junction Dielectric strength box: Buried 1.5m deep water for 24h, the box is applied 15KV (DC) 1min without breakdown, no arc. JHH Series cable junction box Ambient temperature: -40C- + 55C; JHH Series cable junction box atmospheric pressure: 70KPa-106Kpa. JHH Series cable junction box main parameters Model: JHH-6 Material: ABS size: 470 × 170 × 180 (mm) Weight: 4kg maximum number of cores: 336 core structure: Open-type cable hole: maximum 6 hole JHH Series cable junction box Product Features 1. cable access hole Configuration 2 1 pair of rubber apron 2.
