Compared with the CTS 120–1, the CTS 120–2p features a dual-shed (two-petticoat) profile, which considerably increases the creepage distance. This improves its ability to withstand contamination and reduces the risk of flashover in harsh environmental conditions. Manufactured according to EN 60383-1 and EN 60305 standards, the CTS 120–2p provides stable electrical performance, consistent quality, and long service life for utility operators and project contractors. CTS 120–2p offers the same robust 120 kN mechanical strength as the CTS 120–1, but with significantly improved pollution resistance thanks to its double-petticoat design. It is a reliable choice for utilities seeking high-performance insulators capable of long-term operation in challenging environments.
