APPLICATION

PYUNGIL polymeric coupling insulators are used to connect protection devices such as surge arrester and cutouts to electric pole. The coupling insulator has been introduced to cover the weak points of the existing porcelain insulator and bracket. Compared with conventional coupling insulators of porcelain, the polymeric insulators have higher mechanical and electrical performance. The polymeric material (EPDM rubber) that PYUNGIL currently uses has been formulated under its special knowhow for raw material.

The PYUNGIL polymeric coupling insulator has been used for the cable connectors for over 20 years, which proves that the EPDM rubber has dependable quality. The coupling insulator is 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 fiber glass rod.

PYUNGIL insulators are designed and manufactured under the rigid quality compliance of the ISO 9001 quality assurance program.
