1). Problems with traditional zinc oxide arresters. 1. There are potential safety hidden danger at work Currently, zinc oxide arresters are installed in conjunction with monitoring devices, and their structure is shown in the figure below. When the zinc oxide arrester operates, a certain residua...

1)110 ~ 220kV plug cable terminal In the application of GIS combined appliances, the transformer or GIS is sometimes led out from the transformer or GIS directly by high-voltage cable instead of the traditional bushing.There are many types of high-voltage cable equipment terminals, the selection ...

Zinc Oxide Arrester is a lightning arrester with good protection performance. The Zinc Oxide arrester is the most advanced over-voltage protector in the world. This is due to the incorporation of azinc oxide arrester as the core resistor discoThis allows an improvement in the volt-ampere characte...

The difference between Deadbreak Connectors and Loadbreak Connectors Application ● Realize the connection of single-phase or three-phase insulated cables and transformers, switch cabinets, branch boxes and other equipment through 630A prefabricated connectors. ● Suitable for indoor and outdoor in...

1. Classification of 10KV high voltage switchgear: According to the cabinet structure, 10KV high voltage switchgear can be divided into four categories: metal closed interval switchgear, metal closed armored switchgear, metal closed box switchgear and open switchgear. A. Metal enclosed spacer swi...

1, Appearance shape: T Cable Connector  is commonly referred to as the middle branch of the cable, T Cable Connector is from a cable, branch out of a cable, the shape of the joint like T shaped; Elbow connector is different from ordinary cable connector, it’s like elbow. 2, Function and Use...

Fully insulated sulfur hexafluoride closed switch equipment also known as inflatable cabinet, common units are Unit C: load switch module, equivalent to the incoming line of ring network cabinet. V unit: vacuum switch module, equivalent to circuit breaker unit. F unit: load switch fuse combinat...

The secondary winding of current transformer and voltage transformer should be grounded during operation, so as to prevent the high voltage from entering the low voltage through the transformer in series after the insulation of the transformer is broken down, injuring the instrument and operation...

Surge protector is a high-efficiency circuit protector, when it withstand transient high voltage, high energy pulse, fast (10-9s) from the original high impedance to low impedance, and the transient high voltage interference pulse to the predetermined voltage, so as to effectively protect the equ...
