The GN27 40.5 Indoor High Voltage Disconnect Switch represents a completely new and advanced product in the field of electrical equipment. It is specifically designed and suitable for application in power systems that operate at a standard rated voltage of 40.5 kilovolts and use an alternating current frequency of 50 hertz. A key function of this switch is its ability to reliably open and close electrical circuits under specific conditions. While the overall power system remains energized, it performs these operations only when there is no significant electrical load on the circuit being switched. This device is not just an incremental improvement but an upgraded version specifically designed and developed to directly and superiorly replace the older, outdated model it succeeds. Regarding installation, it offers flexible deployment options.For its manual operation, the device is equipped with the CS6 - 2 type mechanism as its standard and default operating mechanism. Furthermore, the entire product series is constructed with a reinforced insulation design concept, which significantly enhances its safety and durability. This robust insulation design gives it a high degree of environmental resilience, enabling it to withstand and operate reliably even in second - level polluted environments.

The GN27 40.5 Indoor High Voltage Disconnect Switch incorporates a variety of contact methods, including rotating contacts, along with an automatic cleaning function and a highly efficient cooling system for optimal performance. The contact points are strategically distributed across two separate planes, which results in a significantly reduced operating torque, excellent withstand voltage capability, and straightforward adjustability. Its design is scientifically grounded and structurally innovative, making it particularly suitable for applications where maximum creepage distance, superior insulation capacity, and the highest level of withstand voltage are critical requirements. Additionally, the shaft frame is mounted on the rotating shaft, which not only extends the equipment's overall service life but also simplifies operational procedures.
