Cemented Porcelain Crossarm Insulators for high voltage lines are used for high voltage overhead transmission and distribution lines for insulating and supporting conductors. They can replace suspension insulators and pin insulators. The all porcelain crossarm insulators are made of solid puncture-proof porcelain parts and metallic accessories through adhesion, which have the advantages of good self-cleaning, simple maintenance, low cost of line materials, safe and reliable operation, etc.
