EPDM Dead-end Insulator Polymeric Insulators

APPLICATION

PYUNGIL EPDM rubber dead-end insulators for 15~35kV have been introduced to cover the weak points of the existing porcelain insulators. Compared with porcelain ones, PYUNGIL polymerics insulators are light-weighted, easy to handle, breakage-resistant, free from crack and also durable. The EPDM rubber that PYUNGIL uses has been made under its special knowhow for raw material. It has been used for the cable connectors for over 20 years, which proves that the EPDM rubber has dependable quality.

The PYUNGIL dead-end insulators are composed of three basic parts of fiberglass rod, which guarantees the high tensile strength, EPDM rubber weather sheds, having excellent dielectric performance and metal end fittings are crimped directly on to the fiberglass rod. The profile and the dimension of the dead-end insulator are obtained and optimized using CAD simulation by experienced engineers.

The PYUNGIL EPDM rubber dead-end insulators have been designed and type-tested at the Korean Electrotechnology Research Institute in accordance with ANSI, IEEE, IEC and Canadian Electrical Association LWIWG-01 (91). The PYUNGIL dead-end insulators are manufactured under the rigid quality compliance of the ISO 9001 quality assurance program.
