1. Purpose and working conditions 1.1 Purpose BJX series explosion-proof junction box (hereinafter referred to as junction boxes) for Class II, places explosive gas mixtures containing Class B, C level below T6 group level groups, and in the exchange of 50Hz rated voltage 380V, rated current up to 1000A following circuit, as the connection of various electrical wiring devices, sub-lines. 1.2 Working conditions a. Altitude does not exceed 2000m; b. The ambient air temperature not higher than + 60 ℃, not lower than -40 ℃; c. Air relative humidity less than 90% (+ 20 ℃ when); d. Vertical mounting inclination of not more than 5 °; e. No significant shake and a strong shock and vibration place; f. No significant damage to the metal and insulation corrosive gases and vapors environment; g. No dripping water and other fluids entering the place; 2, the structure and characteristics 2.1 Model meaning BJX - □ / □ D □ / □ L □ / □ X □ / □ R □ / □ port number into the line / screw right into the line into the line port number / threaded inlet below the line number / threaded inlet on the left into the line number / threaded into the line above the current number of terminals rated junction box main technical parameters in Table 2.2: Rated voltage (V) Rated Current (A) proof mark Inlet and outlet thread 380 220 10,20,30,40,50,60,80,100,120,150,200 ExeIIT6 ExedIICT6 ExdIIBT6 ExdIICT6 G15 G20 G25 G32 G40 G50 G70 G80 2.2 Structure Overview a. Junction boxes in accordance with GB3836.1 ~ 3-2000 standard design and manufacturing, and inspection agencies designated by the state inspection, issued the certificate; b. Junction boxes can be ZL102 cast aluminum alloy molding, or the use of high-strength steel plate welded rot, or economical steel welded inlet and outlet direction, quantity, number of terminals and the nominal diameter can be arbitrarily changed according to user requirements, steel wiring and cable wiring, cabling shall be equipped with cable sealing joints. 3, installation and maintenance of Electrical Engineering Co., Ltd. Yueqing City's official website: http: //www.zgerg.com 3.1 should be checked before installation of the technical data on the nameplate is consistent with the actual situation; 3.2 Check all fasteners Are there loose, if loose should be tightened; 3.3 junction box inside and outside the ground must be good and reliable; 3.4 installation required the cable through seals, metal gaskets, compression nut with compression, guarantee seal and not loose cables, wiring port does not use metal shims to apply seals and sealing; only after opening the lid must first disconnect the power 3.5 maintenance and inspection; 4. Ordering Information Order should include full junction box complete type, name, size and number of orders. Example: BJX-20/30-proof junction boxes, terminal number 20, rated current of 30A, the top line, Inlet thread 1 * G20,1 months, outlet below the outlet thread 2 * G15,4 months.
