Advait Energy Transitions Limited serves as the official marketing partner for Global Insulator Group (GIG), a seasoned player with over 60 years of manufacturing and supply experience. Through Advait, GIG has successfully supplied Glass Disc Insulators to more than 20 countries, catering to projects ranging from 110KV to 500KV.
Global Insulator Group (GIG) is a collaborative effort involving five major enterprises specializing in the production of glass, porcelain, polymer insulators, and linear fittings for power lines, stations, and substations.
GIG operates two primary facilities, specializing in the production of suspension disc-type glass insulators with a capacity of 13 million units annually. This positions Global Insulator Group as a market leader in Russia and the CIS, securing the second-highest sales globally.
The first facility, known as “Yuzhnouralsky Insulators and Fittings Plant, YuAIZ AO,” is situated in Russia, while the second facility, named “Lviv Insulator Company LLC,” is located in Ukraine. They specialize in offering Suspension String Toughened Glass Insulators for High Voltage Transmission Lines (HVTL) and substations, covering a voltage range of 35–1150 kV for AC systems and up to 800 kV for DC lines.
Global Insulator Group provides insulators to major grid companies, oil and gas companies, and railways. With over 600 million insulators in operation across Russia, the CIS, the EU, America, Africa, the Middle East, and Asia-Pacific, GIG prioritizes product quality and customer trust as its core values. All their products adhere to international industry standards, including IEC, BS, GOST R, ANSI, as well as meeting market requirements.
Send InquiryThey’re toughened glass discs stacked together to form insulator strings on transmission towers. Each disc supports the conductor mechanically while electrically isolating the energized line from the grounded tower. You stack them until you have enough electrical distance to prevent arcing, based on voltage and local pollution conditions.
Glass is inherently stronger than porcelain—roughly twice the dielectric strength. You can see through glass, so field teams can spot internal defects without electrical testing. And here’s the big advantage—when a glass disc fails, it shatters and is obviously broken. Porcelain can fail internally without visible signs. That visibility is huge for utilities that value simplicity and transparency. Operators doing routine patrols can spot failures with their eyes. No mystery about whether something’s compromised.
It scales with voltage. 33 kV uses 3-5 discs, 132 kV needs 8-12, 220 kV requires 13-16, 400 kV needs 20-24. Ultra-high voltage 765 kV lines? 35-55+ discs. Pollution severity at the location also factors in—coastal and industrial areas need more discs because pollution creates creepage distance requirements. Every location has different requirements.
We partner with Global Insulator Group, one of the world’s largest glass insulator manufacturers. Their products meet IEC and ANSI standards and have been deployed in over 20 countries. Having a partner with that pedigree backing our products gives customers real confidence in long-term reliability.
