Insulators MSP-20G (SHF-20G) 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.
Insulator MSP-20G (SHF-20G) is the most common pin porcelain insulators for lines with non-insulated and insulated wires.
Analogues of other manufacturers: SDI 30, IF 20.
There are three versions of the insulator by the method of fixing it: with a plastic sleeve with a thread made of composite material, the relevant requirements of the standard SFS (Finland), and BS - small head (UK).
Main characteristics:
- Rated voltage, kV 20;
- The maximum frequency - 50 Hz;
- The maximum allowable voltage, kV 135.
