Porcelain Insulators
Disc, pin, post, shackle, spool and stay porcelain insulators to ANSI, BS and IEC dimensions.
Why This Profile Exists
Distribution networks still specify porcelain for pin, post and spool positions. Huayao supplies both families, so one purchase order can cover a mixed line build.
Load classes in this category run from 40 kN to 120 kN.

Porcelain Insulators Questions
Straight answers to the questions buyers ask before a first order.
Which line conditions suit porcelain insulators?
Distribution networks still specify porcelain for pin, post and spool positions. Huayao supplies both families, so one purchase order can cover a mixed line build.
What is the load range in this category?
Load classes in this category run from 40 kN to 120 kN.
Are dimensional drawings available?
Yes. PDF drawings for the common types are on the downloads page, and a drawing for any listed type can be issued on request before you place an order.
How are these packed for export?
Units are packed in wooden crates built for sea freight. Crate contents and weights are confirmed on the packing list issued with the shipping documents.
Can the goods be inspected before shipment?
Yes. Buyers are welcome at the plant, and third-party inspection by Intertek, BV or SGS can be appointed by the buyer.
