Price of Insulator What You Need to Know Before You Buy

06 25, 2025
Posted By: Peter

When sourcing electrical insulators, especially for 11kV–35kV systems, one of the first questions buyers ask is: What’s the typical price range? The price of insulator varies based on type, material, standard, and application—but there are benchmarks that help guide realistic expectations.

 

Common Market Price Ranges

Based on current export and domestic data, typical insulator pricing falls roughly into these brackets:

Type Voltage Class Estimated Price (USD/unit)

These prices typically apply to:

Batch orders of 100–1000 pcs

Standard interface sizes

Neutral packaging without branding

 

Factors That Affect Pricing

1、Material – Epoxy costs more than porcelain, but offers better tracking resistance

2、Creepage & mechanical rating – More demanding specs mean more resin, larger molds

3、Testing & Certification – Type test reports, batch testing add value (and cost)

4、Order size & frequency – Repeated projects or bulk orders benefit from lower per-unit cost

 

How to Evaluate Beyond Price

Before choosing based solely on cost, ask:

·Is the supplier experienced with my country’s standards (e.g. IEC 60060, IEC 60273)?

·Do they offer drawings and tolerances?

·Is repeatability consistent for phased deliveries?

·What’s the lead time in peak season?
