b. The monthly average relative humidity should not exceed 90%
c. Altitude not exceeding 1000m

Structure and Characteristics
GN28-12 type isolation switch is a combination type, consisting of two types: denominator knife isolation switch and line side isolation switch, mainly composed of contacts, contact knives, insulation components, and frames. The busbar isolation switch, line isolation switch, bypass isolation switch, and one set of grounding knife switches on each side of the switch are assembled on a frame, which not only reduces the volume, but also facilitates the installation of the entire set, eliminating the workload of operators hanging and dismantling grounding wires, as well as personal and equipment accidents caused by improper hanging and dismantling of grounding wires. The isolation switch is equipped with a rotating fully mechanical locking mechanism, which has the characteristics of easy and flexible operation, and reliable five prevention functions.
