The main purpose of electrical grounding is to ensure the safety of personnel. When electrical equipment fails, such as when the insulating layer is damaged and the charged part is exposed, the grounding system can quickly introduce the fault current into the ground.

In power transmission lines, tension-resistant wire clamps are important components that connect wires to poles and towers and bear the tension of wires. The performance of wire clamps will directly affect the safety of the line and the operation and maintenance cost. The tension-resistant wire clamps are divided into bolt type, compression type and preformed type. In this article, we will understand the specific differences between several wire clamps.

In power transmission systems, ACSR is a widely used overhead wire. Preformed armour rods for ACSR conductor are important protective components for ACSR conductors. Through structural design and material selection, the safety performance of power lines can be improved from multiple angles. Protecting the line can not only effectively alleviate the damage of the wire in a complex environment, but also extend the service life of the line and reduce the risk of operation and maintenance.

In the construction of power infrastructure, the installation efficiency and operation difficulty of metal fittings have always been the core issues of concern. Traditional suspension fixtures rely on heavy-duty tools, complex steps and other factors, which will not only slow down the construction progress, but also put forward high requirements for the operating environment and personnel skills. The preformed helical suspension clamp just broke this problem, and with the characteristics of simple operation and easy installation, it has become an important metal tool in the construction of power infrastructure.

High-speed rail catenary is an important carrier for train power transmission. Because of its high strength and good electrical conductivity, ACSR conductors have become common conductors for catenary bearing cables and contact lines. However, in the high-speed rail operating environment, ACSR conductors are facing various challenges such as vibration fatigue, mechanical wear, electrical corrosion and severe weather erosion. At this time, preformed armour rods for ACSR conductor relies on structural advantages and performance characteristics to become an important metal tool to ensure the safe operation of the catenary.

In overhead transmission lines, ACSR conductors that can operate safely are important conductive components and are very important for the stability of power transmission. Preformed armour rods for ACSR conductor, as a protective device designed for ACSR conductors, is a spiral metal component manufactured by the preformed forming process. It realizes multiple protective functions by tightly wrapping the outer layer of the wire, which plays an important role in the construction of power lines.
