Lightning arresters are an important part of the field of electrical protection and are the first line of defense against the destructive power of lightning and surges. When a lightning strike or power surge occurs, the voltage in the electrical system can reach dangerous levels, posing a significant risk to connected equipment. Without proper protection, such sudden power surges can cause equipment failure, data loss, and even fire hazards. However, by installing a lightning arrester, these risks are greatly reduced because the device provides a low-impedance path that safely discharges excess electrical energy to the ground, away from the sensitive components of the system.

Polymer insulator is a type of insulator used in power systems to support and insulate high-voltage conductors. Unlike traditional porcelain or glass insulators, polymer insulators are made of high-quality silicone rubber or other polymer materials and have excellent mechanical and electrical properties. These insulators are designed to withstand harsh environmental conditions such as extreme temperatures, UV radiation and pollution while providing reliable insulation and support for overhead power lines.

A high-voltage fuse is a safety device installed over a drop-out fuse to protect electrical equipment and circuits. When an overload current or short circuit occurs in the circuit, the fuse will blow and cut off the circuit to avoid dangerous situations such as equipment damage or fire. High-voltage fuses are usually used in power systems and industrial equipment. They have higher voltage ratings and can withstand larger current loads. These fuses are usually composed of insulating materials and conductive wires. When the current exceeds the rated value, the conductive wires will melt, cutting off the circuit and playing a protective role.

Oil-immersed fuse is a device used to protect circuits, mainly to prevent overload and short circuit. When the current exceeds the rated value, the fuse wire in the fuse will melt and cut off the circuit, thereby protecting electrical equipment and circuits from damage. The advantages of oil-immersed fuses include high breaking capacity, strong reliability, suitable for high current and high voltage environments, and strong resistance to environmental pollution. It is commonly used in industrial and power systems to effectively protect equipment and personnel. It should be noted that the installation and maintenance of oil-immersed fuses require strict compliance with standards to ensure their normal operation and safety performance.

Drop-out fuse cut our, also known as a fuse switch, is a safety device used for circuit protection. It usually consists of fuse link and fuse holder to automatically cut off the circuit when the current is overloaded to prevent overheating and fire. Drop-out fuses can be installed in circuits to protect electrical equipment and circuits from overloads and short circuits. When selecting a drop-out fuse, you need to consider factors such as the rated voltage, rated current, and breaking capacity of the circuit to ensure that the appropriate model is selected to protect the circuit.
