The switchgear ground knife controller is a vital device used in electrical systems to operate ground knife switches, which are essential for safely grounding equipment during maintenance and servicing. This controller provides reliable and precise control over the opening and closing of ground knife switches, ensuring effective isolation and protection of electrical circuits.

Switchgear insulating material is essential in electrical systems to provide safety, efficiency, and reliability. These materials are typically used in the construction of switchgear assemblies to prevent electrical currents from unintentionally passing through different components, reducing the risk of short circuits, electrical fires, and equipment damage. The most common insulating materials used in switchgear include epoxy resin, glass-reinforced polyester (GRP), and various types of thermoplastics, each selected for their unique properties, such as high dielectric strength, excellent thermal stability, and resistance to moisture and chemical corrosion.

FLN36-40.5D/T630 indoor sulfur hexafluoride (SF6) load switch and FLN36-40.5DR/125 load switch fuse combination are suitable for power stations and industrial electrical equipment with three-phase AC 50/60Hz ring network or terminal power supply. They are used as load control line protection for power systems. The load switch divides and closes load current, closed-loop current, no-load transformer and cable charging current; Combination electrical appliances can break any current under rated short-circuit current and are suitable for electrical complete sets of equipment such as ring main units and box type substations. FLN36-40.5 load break switch and FLN -40.5D load break switch plus fuse combination, can be used to protect  and control the electric equipments for power supply and transformer substations, which is especially suitable  for ring net cabinet, cable branch cabinet and distribution switching substation.

SOLH ITV high flow electro-pneumatic proportional valve is fully interchangeable with equivalent SMC models. Adopting closed-loop pressure feedback system, it accepts DC0–10V voltage, 4–20mA current analog signals, and optional fieldbus communication including CC-Link, PROFINET, EtherNet/IP to achieve stepless, high-precision remote air pressure regulation with ±1% FS control accuracy and IP65 dust & splash-proof protection. Three series cover different flow ranges: ITV1100 for micro low flow, ITV2100 for universal medium flow and ITV3100 for heavy high flow up to 4400 L/min ANR, with adjustable pressure from 0.005 to 0.9 MPa.
