Line post type porcelain insulator
Line column type porcelain insulators are installed in a cantilever column manner to avoid string swing and are suitable for compact line designs. The R Series complies with IEC 60720 and supports horizontal, vertical, and braced column configurations covering 35-220 kV.
Post insulators for compact power transmission designs.
- Cantilever load 3 to 20 kN
- Voltage level 35 / 66 / 110 / 220 kV
- Horizontal, vertical, support configuration
- IEC 60720 Type test

FAQ
Frequently asked questions
Which standards do Line post type porcelain insulator comply with?
All Line post type porcelain insulator from InsulatorX are type-tested to IEC 60720. Type-test reports are issued by independent laboratories including CEPRI and KEMA, and buyer factory audits or witness testing are welcome.
What ratings are available for Line post type porcelain insulator?
Line post type porcelain insulator are supplied across 35–110 kV, 3–20 kN. Send us your line voltage, span tension and creepage requirement and our engineers will size the right model with margin.
Which Line post type porcelain insulator models can I order?
Catalogue models include R3ET105N, R6ET125N, R12.5ET150N, R20ET175N. Custom dimensions, shed profiles, creepage extension and connection markings are available on request.
Can Line post type porcelain insulator be supplied for coastal or heavy-pollution lines?
Yes. We raise creepage distance and offer fog / anti-pollution profiles or hydrophobic silicone housings, sized to your site pollution class — typically class III to IV near the coast.
How do I request a quotation and what is the lead time for Line post type porcelain insulator?
Email your specifications — voltage, mechanical load, creepage, environment, quantity and INCOTERM — to support@insulatorx.com. We reply within one business day; lead time is 4 to 6 weeks for standard models and 8 to 14 weeks for custom designs, shipped EXW / FOB / CIF / DDP.
