CTV 254 AХE 14 Ukraine Type Glass Insulator

CTV254 is a classic toughened glass suspension insulator, often used in strings for 33kV–132kV lines depending on string length and mechanical load. Its disc design ensures efficient load-distribution, while the toughened glass material provides high impact resistance and rapid failure identification through the “zero-value” breakage characteristic.


Manufacturers like Nooa Electric produce CTV254 insulators for global transmission projects, offering consistent quality and compliance with IEC, ANSI, and utility-specific standards.

Design Structure and Material Properties

The CTV254 insulator typically features:
Toughened borosilicate glass with high mechanical tensile strength
Hot-dip galvanized steel fittings (ball & socket or tongue & clevis type)
Standard disc diameter of approximately 254 mm in line with IEC profile sizes
Clear or green-tinted toughened glass for enhanced visibility and aging resistance
The toughened glass material gives the insulator a smooth, non-porous surface that repels dust, salt, and industrial pollutants naturally—ideal for desert, coastal, and industrial zones.

What Our Clients Say

Glass Electrical Insulators

FAQ: CTV254 Glass Insulator

1. What voltage level is the CTV254 suitable for?
Depending on string length and design, the CTV254 is commonly used for 33kV, 66kV, 110kV, and 132kV lines.

2. How does toughened glass compare to porcelain insulators?
Toughened glass offers higher visibility of damage, better pollution performance, and more consistent quality than porcelain.

3. What is “zero-value detection”?
When the glass disc breaks, it shatters into small pieces but still hangs in place. The broken disc is easy to spot, allowing quick replacement without electrical failure.

4. Does Nooa Electric provide complete insulator strings?
Yes. Nooa Electric supplies complete glass insulator strings, including tension hardware, suspension fittings, and conductor clamps.

5. Can CTV254 be used in coastal or industrial pollution zones?
Yes, its smooth glass surface provides excellent anti-pollution flashover performance, making it ideal for harsh environments.
