Porcelain Insulators For Switchgear Manufacturers
GOST material clauses that general suppliers will not commit to
Pain points
What Gets In The Way
- GOST material clauses that general suppliers will not commit to
- Threaded cubicle seats that flange-mount post insulators will not fit
- Wall penetrations that have to be insulated and sealed at the same time
- Post insulators flexing under busbar short-circuit forces
Requirements
What This Sector Needs From A Supplier
- Post insulators with published cantilever and torsion ratings
- GOST ceramic, fitting alloy and bonding cement clauses met by specification
- Round and oval flange wall bushings to match existing openings
- Indoor bushings with a stated bearing capacity

Questions
Switchgear Manufacturers Questions
Which GOST standards do the post insulators meet?
Group 120 electrotechnical ceramic to GOST 20419-83, AK12 aluminium alloy fittings to GOST 1583-93 and PTs-500 DON bonding cement to GOST 10178-85, with silicone sealed joints.
What cantilever and torsion ratings are published?
4kN breaking force with 100N.m torsion on the C4-80 II, and 8kN bending strength on the J8-125.
Can you supply oval flange wall bushings?
Yes. Construction type I with the oval flange is produced, along with round flange versions.
What bearing capacity do the indoor bushings have?
12.5kN on the IP-10-100, with a trough type connection method.
