Glass Insulators: The Guardians of Power Transmission
In the vast network of power transmission systems, glass insulators play a crucial role in ensuring the safe and efficient delivery of electricity. As a leading provider of high-quality power transmission solutions, we are proud to offer a range of glass insulators that are designed to meet the most demanding requirements of modern electrical grids.
JDC-01 Thermal Explode Type Disconnector for Lightning Arrester Product Description
Product Overview
JDC-01 Thermal Explode Type Disconnector is an intelligent protection device designed for lightning arresters. It aims to solve the industry problem that traditional lightning arresters cannot be quickly isolated after failure and require power outages for maintenance. Through innovative thermal trigger mechanism and structural design, JDC-01 can automatically cut off the fault circuit when the internal temperature of the lightning arrester rises abnormally due to lightning strike, overload or aging, ensuring the safe operation of the power system, while achieving "non-stop maintenance", significantly improving the reliability and operation and maintenance efficiency of the power grid.
12kV High Voltage Ring Main Unit Fuse Protection Oil-immersed Transformer Current Limiting Fuse Product Introduction
12kV High Voltage Ring Main Unit Fuse Protection Oil-immersed Transformer Current Limiting Fuse is an integrated protection device designed for medium and high voltage power systems, combining the insulation and heat dissipation advantages of oil-immersed transformers with the fast fault isolation capability of current limiting fuses. This product is widely used in urban distribution networks, industrial parks, new energy power stations (such as photovoltaic or hydro-power stations) and other scenarios, aiming to improve the stability and safety of power systems and reduce the risk of equipment damage caused by faults.
High-voltage electrical products Outdoor lightning arrester: "Lightning Guardian" of power system
