Insulator Procurement Overview
Insulators are core components in power transmission and distribution systems, where they support conductors while providing electrical isolation. As Bangladesh expands its grid and replaces aging facilities, demand for multiple insulator types continues to rise. This article reviews key procurement trends captured through the Public Procurement Monitoring System (PMS) and outlines practical market-entry approaches for Korean suppliers.
Demand by Insulator Type
Insulators used in Bangladesh broadly fall into three categories: porcelain, glass, and composite or polymer types. Porcelain insulators have historically dominated the market, but composites are gaining share quickly because of their lighter weight and stronger resistance to pollution. In coastal and industrial zones in particular, composite insulators are increasingly treated as essential rather than optional.
| Type | Application | Voltage Class | Annual Demand | Main Import Sources |
|---|---|---|---|---|
| Porcelain Suspension | Transmission lines (132-230kV) | 132-230kV | Approx. 800,000 units | China, India |
| Porcelain Pin Type | Distribution lines (11-33kV) | 11-33kV | Approx. 1 million units | China, India, Pakistan |
| Glass Suspension | Extra-high-voltage transmission (230-400kV) | 230-400kV | Approx. 200,000 units | France, China |
| Composite | Across all voltage classes | 11-400kV | Approx. 500,000 units | India, China, Turkey |
