China Elbow Surge Arrester Loadbreak Connector - Reliable Protection from Top Suppliers and Factory Options

Introducing our state-of-the-art Elbow Surge Arrester, designed to provide effective shielded deadfront arrester protection using advanced metal oxide varistor technology. This product features parking stand arresters and is specifically engineered for seamless installation on standard separable connector bushings, making it an ideal choice for underground distribution systems, Installation at the open point of the underground system is crucial to prevent voltage wave doubling. Additionally, it can be strategically placed at the midpoint to safely discharge voltage reflections from the open point arrester, Our elbow surge arrester is constructed with high-quality peroxide cured EPDM rubber, ensuring complete shielding with a molded conductive EPDM jacket. This innovative design facilitates the dead front concept and ensures that the product is fully submersible for diverse applications, We offer three reliable ratings: 27kV, 18kV, and 10kV, each compatible with nominal 35kV, 25kV, and 15kV underground distribution systems, respectively. These designs adhere to the standard ANS/IEEE 386 separable connector interface, ensuring excellent compatibility with leading interface suppliers, As a trusted China factory and supplier, we are committed to delivering high-quality products to meet your underground protection needs while maintaining superior performance and reliability

Product Overview

Load break Elbow Connector is a fully-shielded and insulated plug-in termination for connecting underground cable to distribution power system of pad-mound transformer, surrounding power supply branch box, cable branch box equipped with load break bushings. The elbow connector and bushing insert comprise the essential components of all load break connections. It can meet the demand of lines in nuclear.

The Load break Elbows are molded using high quality sulfur-cured insulation and semi-conduction EPDM rubber. Standard features include a copper connector, tin-plated copper load break probe with an ablative arc-follower tip and stainless steel reinforced pulling-eye. An optional capacity test point, made of corrosion resistance plastic is available for use with fault indicators.
