Key Features:

• The product is specifically designed for full compatibility with T-plug type terminations, specifically Eaton’s Cooper DTS624S model. Thanks to its direct-mounting capability, the product ensures a solid electrical contact, minimizing contact resistance and arcing at the connection point. This not only enhances operational efficiency but also minimizes the risk of fire, explosion, or cable damage during operation.
• In addition, the mechanical structure of the Deadfront Surge Arrester is precisely engineered for quick installation and easy removal, providing convenience for maintenance or replacement without affecting the structure of the operating cable system.
• One of the most outstanding features of the Deadfront Surge Arrester is its powerful discharge capability with a nominal current of 10kA. This figure demonstrates that the product is fully capable of withstanding high voltage surges caused by lightning strikes or system faults, especially in environments with a high risk of lightning or across long power grids.
• Equipping DSAs at cable terminations provides effective protection for downstream equipment, minimizes the risks of fire, short circuits, and ensures the operational continuity of the electrical system.
• With a rated voltage range from 9kV to 45kV, the Deadfront Surge Arrester (DSA) can be flexibly applied across various electrical system levels without requiring changes to the technical solution. This allows contractors, engineers, and investors to easily synchronize equipment, save selection and implementation time, and optimize inventory management in large-scale projects.
• The product is manufactured according to IEC 60099-4 standards, meeting strict requirements for insulation capability, dielectric strength, operational stability under high voltage, and safety during lightning discharge. This is an important certification that affirms the quality and reliability of the equipment in practical use.
• The T-plug-mounted design allows for the quick installation or replacement of the surge arrester without requiring complex technical skills or specialized tools. This helps shorten construction time and reduce maintenance costs throughout the equipment’s lifecycle.
