Proximity switch; It is mainly used for industrial automation and semi-automatic control system to realize speed and position, limit position detection and counting control. It is a new type of sensor switch element, and it does not detect mechanical contact in object link at all. When the object approaches the detection distance of the switch, the switch control signal is sent. Proximity switch is also called proximity sensor, also called contactless travel switch. In addition to completing travel control and limit protection, or non-contact detection device

The connection of bus bars to voltage distribution devices at all levels in the substation, as well as the connection of electrical equipment such as transformers and corresponding power distribution devices, mostly uses bare conductors or stranded wires with rectangular or circular sections, which are collectively called bus bars. The online teaching of electrical design is taught by the birds on trees. Bus duct is a power distribution device with high efficiency to transmit current, which is especially suitable for the economic and reasonable wiring needs of increasingly high buildings and large-scale factories. With the emergence of modern engineering facilities and equipment, all walks of life

Wall bushing is a high-quality hardware pipe fitting for structures. Generally, only the research and development unit with ultra-high building science accumulation can produce standard wall bushing. It is widely used in steel and sewage treatment units. Wall bushing must be used in many non concrete walls that are converted to concrete walls.

Composite test insulator is composed of iron cap, porcelain bottle sleeve pipe fittings (suspension type or silicone rubber) and steel foot (conductive rod), and is cemented into a body with cement cement. This product adopts international and advanced cylindrical head structure, which is characterized by small head size. Light weight, high strength and large creepage distance. It can save metal materials and reduce line cost. In order to meet the needs of live working, the traditional domestic structure shape is adopted on the brim.
