Why Choose the 15KV 200A Elbow Arrester 17/45 for Underground Distribution System Protection?

In underground power distribution systems, especially those involving pad-mounted transformers, entry cabinets, and vault switchgear, surge protection is vital to ensure long-term performance and safety. The ENOCH 15KV 200A Elbow Arrester 17/45 is specifically engineered to provide shielded dead-front protection against transient overvoltages, protecting essential infrastructure while extending the service life of cables and equipment.

This elbow arrester integrates a high-performance metal oxide varistor (MOV) module into a robust rubber elbow housing. The body is molded from high-quality, peroxide-cured insulating and semi-conducting rubber, ensuring excellent dielectric strength, weather resistance, and mechanical durability. Whether exposed to moisture, confined spaces, or challenging underground conditions, the ENOCH elbow arrester continues to perform with consistency and reliability.

Another key advantage of the ENOCH 15KV 200A Elbow Arrester is its compliance with the IEEE 386 standard. This ensures mechanical and electrical compatibility with a wide range of separable insulated connector systems. In practical terms, this means the product is fully interchangeable with other arresters that meet the same standard—an essential benefit for operators who manage diverse or existing systems and want to avoid compatibility issues.

Designed with a dead-front, fully shielded construction, the arrester enhances operational safety by ensuring all energized parts are enclosed. This feature is especially beneficial during installation or maintenance work in confined or high-moisture environments commonly found in underground utility spaces. Additionally, the arrester supports multiple installation configurations. It is suitable for use at both ends of an open point in a loop system or at the end of a radial system, providing essential surge protection at vulnerable points in the distribution network.

From a technical standpoint, the product offers a voltage rating of 15KV and a current rating of 200A. It features the Elbow Arrester 17/45 design type and uses a precision-engineered MOV module to reliably suppress overvoltage events such as those caused by switching surges or lightning strikes. These capabilities make it an essential component for operators seeking cost-effective protection and long-term reliability in medium-voltage underground systems.

In conclusion, the ENOCH 15KV 200A Elbow Arrester 17/45 is a dependable and standards-compliant solution for underground surge protection. Its combination of durable materials, proven MOV performance, and compatibility with IEEE 386 systems makes it a top choice for engineers and utility providers. For robust and reliable protection, the ENOCH elbow arrester is a smart investment in the safety and longevity of your electrical infrastructure.
