Product Description

| Company Profile

Nanjing Rainbow Electric Co., Ltd. (NJREC) is a leading Chinese manufacturer and supplier of electrical insulators and transformer bushings.NJREC undertakes and offer the reliable electrical insulators for transmission lines and substations. We also provide one-stop solutions for distribution & power transformers, pad-mounted transformers and wall-mounted applications.

| Product Introduction

As a linchpin for power transmission systems, double - shed disc suspension - type tempered glass insulators are indispensable for delivering both electrical insulation and mechanical stability.

Key Features & Benefits:

✔ Enhanced Electrical Insulation – The double-shed structure extends the surface leakage path, preventing flashovers caused by contamination and wet conditions.
✔ Superior Pollution Resistance – Ideal for medium to heavily polluted areas, reducing maintenance frequency compared to single-shed designs.
✔ Self-Cleaning Effect – Angled sheds promote rainwater runoff, minimizing dirt accumulation and sustaining long-term performance.
✔ Mechanical Durability – Manufactured from tempered glass, it withstands high mechanical loads and extreme weather conditions.
✔ Wide Application – Used in overhead transmission lines, substations, and transformer bushings, ensuring stable power flow and grid reliability
