Available to common models UGSP monitoring shielded cables in the wiring for the power supply of mobile substation. Model meaning BHG2-400 / 10KV-4G cable boxes, high voltage junction box BHG2-400 / 10KV-4G cable boxes, high voltage junction box BHG2-400 / 10KV-4G cable boxes, high voltage junction box BHG2-400 / 10KV -4G cable boxes, high voltage junction box 3.4 proof mark: "ExdI" 3.5 Explosion-proof type: flameproof 4, junction boxes suitable working conditions following the work environment: 1. Altitude less than 1000m; 2. ambient pressure ( 86 ~ 110) kpa; 4. air relative humidity less than 98% (+ 25 ℃);; 3. the ambient temperature (-20 ~ + 40) ℃ 5. coal mine methane and coal dust has an explosive mixture; 6. No significant shaking and severe shock and vibration environments; 7. No damage metal and insulation of gases and vapors environment; 8. Pollution degree: 3; 9. Installation category: Ⅲ class. 5, the structure of the junction box is by the housing, cover and wiring porcelain stand (see Figure 1). For preventing cable pull-out of the casting plate is designed with a curved groove, the pressure line to improve the reliability. Porcelain pedestal selected excellent performance high-voltage ceramic powder baked, with a strong insulating properties. Clearances between the junction box inside a charged body, and creepage distances are in line with the standard requirements.
