As one of distribuiton insulators or IEC ceramic pin type insulator, IEC P-33-Y porcelain pin insulators / pin type ceramic insulator plays a role in hanging the electric conductors and insulation for distribution power system.
Ceramic pin type insulator mechanical strength test should be done under apply certain electricity, that is to do combine mechanical and electrical strength tests. IEC P-33-Y porcelain pin insulators are a semi-conductor grey glazed porcelain pin type insulator, and its creepage distance is 630mm.

IEC P-33-Y porcelain pin insulators or pin type ceramic insulator quality control:
Asiatic has the requisite infrastructure to carry out routine tests on the Anti-pollution IEC P-33-Y porcelain pin insulators as desired by international standards like: Dry power frequency voltage test, cantilever failing load test, lightning power withstand voltage test, U.V. weathering tensile test etc. as per IEC or ANSI.
According to IEC standard, IEC P-33-Y porcelain pin insulators mechanical rated strengths have 4KN, 6KN, 8KN, 10KN, 12KN, 12,5KN, 13KN. In the accordance of ANSI C29.5 and ANSI, ceramic or porcelain pin type insulator usually used cantilever failing load has C29.6, 2500 lb/11KN, 3000lb/13KN.
