Bus copper bar bus duct machine

overview
CCKX18 series busway is a high-strength fully enclosed reinforced insulation type. The product shell is made of galvanized steel coiled into a corrugated cover, and the busbar conductor is fixed with a corrugated cover, which can withstand the thermal stress and electric power caused by high short-circuit current. CCKX18 reinforced insulating aluminum alloy shell Busway and anti-corrosion busway have the characteristics of common and reliable structure, good appearance and light weight. Anti-corrosion busway is widely used in the ideal choice of power transmission and distribution equipment in harsh working conditions such as petroleum and chemical industry. Executive standard: GB 7251.2-1997, JB/T 9662-1999, GB 7251.2-1997, GB 14048.1-2000, GB/T 4942.2-1993 Main features: ⚫Busway conductors are made of copper, in line with GB5585.1 -5585.3 standards, Contains 99.9% copper. The surface of the conductor joint is tin-plated or silver-plated, with good contact, low heat generation, and safe and reliable use. ⚫The service life of the busway depends on reliable and high-quality insulating materials and processes. CCKX18 series adopts special rubber insulating tubes and epoxy fluidized powder for overall insulation (rubber insulating tubes have obtained national patents, patent number: ZL97239614.4). Two Both insulation methods are internationally advanced and belong to Class B insulation materials. The long-term working temperature can reach 130°C, the insulation breakdown strength is high, the impact resistance is flame retardant, and the aging resistance life exceeds 50 years. ⚫A unique connection method is adopted, and the connection of each functional unit adopts a plug-in movable connector (has obtained a national patent, patent number: ZL95207020.0). ⚫Double Side connecting method doubles the area of ​​the contact surface and doubles the contact resistance, thereby reducing the temperature rise of the busbar. ⚫The unique butterfly washer and high-strength single bolt ensure the balance of force on the connection surface. ⚫Due to the non-porous connection between the kinematic joint and the functional unit, the stretching length of the system can be automatically compensated as the temperature changes. ⚫The busway can be pulled out from the adjacent busbar at no-load to isolate the faulty area and reduce the time and scope of power failure. ⚫The casing is designed as an effective grounding system, the grounding resistance value is much smaller than the standard, and a grounding busbar with 50% relative capacity is configured.main technical data
