Low Voltage Porcelain Bushings in DIN standard A tried-and-tested low-voltage bushing for distribution transformers applications may be a rod of conducting material inserted into a porcelain tube. This has a central current-carrying bolt, usually of copper, and the insulation is provided by a com...

We all know what transformers are made of; That includes the tap switch we share today. Let us know what the tap switch in the transformer is used to do? First of all, let’s understand the main components of the transformer: 1. Transformer body: composed of iron core, winding, wire and ins...

What is a current transformer? A current transformer is an instrument that converts a large current on the primary side into a small current on the secondary side based on the principle of electromagnetic induction. A current transformer consists of a closed iron core an...

15kV 200A Load break Elbow Connector is a fully-shielded and insulated plugin termination for connecting underground cable to distribution power system of pad-mound transformer, surrounding power supply branch box, cable branch box equipped with load break bushings. The elbow connector and bushin...

AHBLQ-17/50 Deadbreak T Rear Arrester Product introduction: AHBLQ-17/50 Deadbreak T Rear Arrester can provide reliable overvoltage protection for the electrical system. The shielding type followed by the outer semi-conductive layer of the arrester ensures the personal safety of the installation ...

The difference between zinc oxide arrester and elbow arrester 1. (1) Working principle of valve-type arrester: When the system is normal, the spark gap isolates the valve plate resistance from the working bus, so as not to burn out the valve plate resistance due to the current generated in the va...

With the rapid development of new energy, China has become the largest country of hydropower, wind power, solar power generation, and renewable energy accounts for continuous increases. To make these volatility, intermittent clean electric energy, upgrade the power transmission technology is impe...

Power Fuse is a generally accepted means to protect power transformers in distribution substations. The main purpose of the Power fuse is to provide a permanent fault interruption. Fuse is an economical alternative to circuit switcher or circuit breaker protection. Fuse Fuse protection is usually...

A fuse is an insurance policy that burns wires to prevent too much electricity. In fact, the fuse is a kind of easy to burn fine alloy wire, it can only pass through the normal electric current, when the electrical flow exceeds a certain value, it will heat and fuse and cut off the power supply, ...

With regard to the product safety of the device and the life/reliability of the fuse, the right choice is important. Safety principles are considered only when properly selected and used in an agreed manner the determination function of the fuse chain can be used as a protective part. “Any ...

Fuse, installed in the circuit equipment, to ensure the safe operation of circuit components, the use of high resistivity, low melting point of silver copper alloy made, in the circuit work, the external working environment temperature, the internal pulse current and so on will affect the service...

1. Normal operating current. 2. The voltage applied to the fuse. 3. The current that needs to be disconnected from the fuse. 4. Minimum and maximum time allowed for abnormal currents to exist. 5. Ambient temperature of the fuse. 6. Pulse, Impact Current, inrush current, start current and circuit ...
