Escopo de Aplica\u00e7\u00e3o<\/h3>\n\n\n\n
This contact box is applicable to 24kV class truck-type withdrawable switchgear and is commonly found in power distribution systems, industrial substations, high-rise building distribution rooms, mining and industrial enterprise distribution systems, and similar electrical installations. It functions as an insulation protection and connection transition component for internal switchgear contacts, providing reliable insulation assurance for the switching and isolation of high-voltage circuits, and accommodating medium-current power transmission requirements.<\/p>\n\n\n\n

Recursos do Produto<\/h3>\n\n\n\n
Superior insulation performance: Formed using the epoxy resin APG process, the product exhibits excellent insulation properties, effectively isolating high-voltage circuits and preventing leakage and short-circuit risks, with high resistance to impulse overvoltage;<\/p>\n\n\n\n
Robust and durable structure: The monolithic molded construction provides high mechanical strength, capable of withstanding both mechanical and electrical stresses within the switchgear enclosure, resulting in an extended service life;<\/p>\n\n\n\n
Well-controlled temperature rise: Under continuous rated current operation, the temperature rise at the terminal outlet does not exceed 65\u00b0C, effectively ensuring safe equipment operation and preventing faults caused by excessive temperature rise;<\/p>\n\n\n\n
Easy installation: Standardized mounting dimensions compatible with conventional 24kV centrally-mounted switchgear, facilitating on-site installation and replacement;<\/p>\n\n\n\n
Corrosion and oxidation resistance: The epoxy resin material provides excellent resistance to corrosion and oxidation, enabling reliable performance across a wide range of demanding electrical environments;<\/p>\n\n\n\n
Excellent surface finish: Smooth, burr-free surface for convenient installation, with good flame-retardant and wear-resistant characteristics.<\/p>\n\n\n\n
