The important role of shock-proof hammer for electric hardware

The electric shock-proof hammer produced by the fastener is composed of a certain quality of heavy hammer, zinc steel strand and wire clamp with high elasticity and high strength. On high-voltage overhead lines, a small hammer is often hung on the conductor near both sides of the insulator. This small hammer is called an anti-vibration hammer, which is set up to reduce the vibration of the conductor caused by wind. The high-voltage overhead line has a high rod position and a large stop distance. When the conductor is affected by wind, it will vibrate. When the wire vibrates, the working conditions at the wire suspension are unfavorable. Due to multiple vibrations, the wire will undergo fatigue damage due to periodic bending. When the overhead line spacing is greater than 120 meters, the general use of anti-vibration hammer shockproof.

What is the configuration of the pole

The configuration of the pole includes the following: The pole breaker is a switching device installed on the pole, which is used to cut or connect the line, and can be switched manually or automatically in the event of a short-circuit fault. Intelligent vacuum circuit breaker can be manual, electric, remote control operation and remote host operation, by the body, operating mechanism, controller. In addition, communication lines can also be set up on the poles, but it is necessary to pay attention to the safety of communication lines and power lines with the pole. The configuration of transmission and distribution lines should be differentiated according to regional planning, economic development and operating environment, so as to improve the reliability and economy of power supply.

The circuit breaker can directly start the equipment, can the contactor be omitted?

Why use contactors and buttons to control the motor instead of directly using circuit breakers? Some equipment can obviously use a circuit breaker to start the equipment directly. Why use contactors? I took the question to many old electricians, all of them looked surprised, then smiled awkwardly. To put it bluntly, everyone knows a little about this, but they can't fully summarize the reasons. The following from several aspects to analyze, circuit breakers and contactors can choose one of the two: The main function of the circuit breaker is to provide protection to the circuit, and the function of the contactor is mainly to control the circuit.

High temperature line how to store and deposit?

High-temperature wire is a common high-temperature wire. The working temperature is about minus 80 degrees to minus 250 degrees. It is made of solid or stranded silver-plated or nickel-plated copper wire. It is mainly composed of conductor and insulating layer. The insulator is processed by PFA Teflon. Then storage and storage will definitely be involved when using high-temperature wire. How to store and store high-temperature wire? Next, let's learn about it.
