Insulators MSP-20G1 (SHF-20G1) used for isolating and fixing the wires on overhead power lines with voltage up to 20 kV and frequency up to 100 Hz at an ambient temperature of -60 C to -50 C.
The letter "G" in the marking of the insulator denotes the index modification insulator and indirectly characterizes the period of release.
There are three versions of the insulator SHF20G1 by the method of fixing it: with a plastic sleeve with a thread made of composite material meets the requirements of the standard SFS (Finland), and BS - small head (UK).
Rated voltage is 180 kV.
The maximum frequency is 50 Hz.
