components of the connectors; current is transmitted along the series-connected connector channel to provide parallel power supply across multiple circuits.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Electric field control: The built-in semiconductive shielding layers within the connectors uniformly distribute the electric field, preventing partial discharge caused by electric field concentration and ensuring insulation integrity.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Protection and safety: The fully sealed structure prevents ingress of moisture and dust; IP67 protection enables operation in harsh environments including high humidity and heavy dust; with the connector housing grounded, maintenance personnel face no risk of electric shock upon

substations: Multi-circuit connections on the high-voltage side within pad-mounted substations; compatible with the harsh operating environments of both indoor and outdoor pad-mounted substations.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Cable junction box bus bar: Multi-circuit tapping within cable junction boxes, enabling parallel power supply for multiple cables without the need for additional cable trays or bus bar bridges.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Power distribution systems in industrial and mining enterprises: Bus bar connections for power distribution equipment in humid, dusty, and corrosive environments, enhancing the system&#8217;s resistance to contamination and corrosion.<\/p>\n\n\n\n<h2

in accordance with process requirements, ensuring that stripped lengths and dimensions conform to connector specifications to avoid damage to the cable insulation.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Clean the interface before connector installation, apply silicone grease evenly, and ensure the connector is fully seated with a reliable, secure connection free of looseness or misalignment.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Grounding leads must be reliably earthed to ensure the connector housing is maintained at ground potential, achieving touch-safe operation.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">After installation, inspect the connector sealing surfaces to confirm no gaps or damage, ensuring IP67 protection performance is maintained.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">\u7ef4\u62a4\u6307\u5357<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Periodically inspect the external condition of connectors for cracks, damage, discharge marks, or contamination buildup, and verify that connections are tight and free of looseness.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Periodically test insulation resistance and contact resistance of connectors to confirm performance meets requirements and to identify potential faults in a timely manner.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Clean connector surfaces to remove accumulated dust and contamination; prevent oil and chemical substances from corroding the rubber connector housing.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">When abnormalities such as cracks, physical damage, discharge, or insulation resistance exceeding permissible limits are detected, the affected connectors must be replaced promptly; continued operation with known defects is strictly prohibited.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">\u9002\u7528\u7684\u6807\u51c6\u548c\u8ba4\u8bc1<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">International standard: IEC 60840, Test
