Nantong proof junction box price

Proof junction box is special equipment used various high-risk places, and civil junction boxes ratio, which is the result of the transformation from a variety of explosion-proof junction box with explosion-proof function. Die-cast aluminum or stainless steel welding, explosion-proof junction box according to classification: According to the functional material into the form: the explosion-proof junction box, aluminum explosion-proof junction box, stainless steel explosion-proof junction box, steel explosion-proof junction box; Depending on the structure is divided into: a wall-mounted vertical explosion-proof junction box and junction box. Proof junction box series: shell with impact-resistant glass fiber reinforced polyester material made of all metal parts are corrosion-resistant. Combination of surface cover and base are designed to bump shape with silicone rubber seal structure to ensure the IP65 protection rating. As the connection of various electrical equipment and instrumentation in voltage 220V / 380V line point line, wiring purposes. Existing junction box in three sizes: built self-locking screw terminals specifications 2.5-3.5 mm, the introduction of a fixed wire connection. Different types and specifications of cable glands meet different cable entry: Plastic cable gland entry system (mounting end) is a metric thread in the fortification loose jaw, with good mechanical characteristics. Unused cable entries available space plug plug seal, retrofit and expand facilities for the future more convenient. Proof ceiling fan applies to the surrounding medium containing ⅡA, ⅡB level temperature groups T1 ~ T4 group explosive gas mixtures place as the ventilation cooling in AC 50Hz, voltage to 200V circuit. Work reliably under the following conditions: 1, altitude does not exceed 2000m; 2, ambient operating temperature is -20 ℃ ~ + 40 ℃; 3, ambient air relative humidity less than 95% (+ 25 ℃) 4, containing ⅡA, ⅡB Temperature Class T1 ~ T4 group explosive mixture properties; 5, no significant shake the shock vibration place; 6, no damage to the insulation of gas or vapor environment; 7, no dripping place; 8, pollution degree 3; 9 , installation category Ⅱ class
