Insulators for Power Distribution Networks
Distribution networks buy insulators in volume and fit them fast. What matters is dimensional consistency between batches, the right pin height, and enough leakage distance for the air the feeder actually runs through.
Talk To An EngineerWhat Goes Wrong on These Assets
- Pin insulators overloaded at line angles
- Secondary spools that do not seat in existing racks
- Guy wires left metallically continuous to the anchor
- Leakage distance specified for clean air on a feeder that runs past a quarry
What Buyers Need From a Supplier
- ANSI dimensional references held consistently across batches
- Light units that crews can handle at height
- One supplier covering pin, post, spool and strain hardware
- Volume supply against a delivery schedule

Questions About This Application
Can we order across several types on one shipment?
Yes. Send the quantity mix and destination port and we will quote the container loading and delivery schedule as one order.
How consistent are the dimensions between batches?
Production runs to the ANSI dimensional references under an ISO 9001:2015 quality system, and each unit carries production identification so a batch can be traced.
What leakage distance do we need on a distribution feeder?
It follows from your pollution class in mm per kV. Per-unit leakage figures of 305 mm and 533 mm on pin types, and 559 mm and 737 mm on line posts, let you complete that check.
