1. Produk Oorsig Produk Oorsig
The PGS-12kV Pole-Mounted Load Switch is a key switching device in the 12kV medium-voltage distribution network, mainly applied to outdoor overhead pole-mounted installation scenarios. It is designed to realize on-load switching of normal load current in the distribution line, and can quickly isolate the fault section when the line fails, effectively reducing the power outage range and improving the power supply reliability of the distribution network. The product integrates a vacuum arc-extinguishing unit, an operating mechanism, an insulation support and a shell into one, with a small volume and light weight, which is convenient for hoisting and pole-mounted fixed installation. It supports manual operation (insulated operating rod) and electric remote operation (opsioneel), which can meet the operation requirements of conventional distribution networks and intelligent distribution networks. The insulation system adopts high-quality hydrophobic silicone rubber, with a large creepage distance, which can effectively prevent pollution flashover accidents and ensure the safe and stable operation of the equipment in outdoor environments for a long time.
PGS-12kV 柱上负荷开关是 12kV 中压配电网的关键开关设备，主要应用于户外架空柱上安装场景，用于实现配网线路中正常负荷电流的带负荷分合，且能在线路故障时快速隔离故障区段，有效缩小停电范围，提升配电网供电可靠性。产品将真空灭弧单元、操动机构、绝缘支撑及外壳集成一体，Klein grootte、ligte gewig，便于吊装及柱上固定安装；支持手动操作（绝缘操作杆）和电动远程操作（可选配），可满足传统配电网与智能配电网的操作需求。绝缘系统采用优质憎水性硅橡胶，爬电距离大，Kan effektief besoedeling-oorslaan-ongelukke voorkom，保障设备在户外环境中长期安全稳定运行。
