Toughened Glass Insulators CTS 70–1, CTS 120–1, CTS 120–2P

Toughened glass insulators are essential components in modern overhead distribution systems, offering high mechanical strength, excellent dielectric performance, and long-term durability. Models such as CTS 70–1, CTS 120–1, and CTS 120–2P are widely adopted in European and international markets for 10–35 kV networks. As a leading manufacturer, Nooa Electric provides consistent quality and compliance with international standards such as EN 60383-1 and EN 60305.

CTS 70–1 Toughened Glass Insulator

A 70 kN pin-type toughened glass insulator ideal for 10–20 kV distribution lines, offering reliable electrical and mechanical performance.

The CTS 70–1 is a widely used toughened glass pin-type insulator with a mechanical failing load of 70 kN, making it suitable for standard mechanical load applications in medium-voltage distribution networks. Its toughened glass body ensures high tensile strength, superior weather resistance, and a natural safety shattering feature that enables easy visual inspection.

This model is typically installed on crossarms mounted on wooden or concrete poles. With optimized creepage distance and excellent dielectric properties, the CTS 70–1 performs reliably in rural, suburban, and moderate contamination environments. Nooa Electric manufactures this model with stringent quality control, ensuring long-term stability and low maintenance needs.

CTS 120–1 Toughened Glass Insulator

A 120 kN high-strength insulator designed for harsh mechanical loads and 20–35 kV distribution systems.

The CTS 120–1 is engineered for applications requiring higher mechanical performance. With a 120 kN mechanical failing load, this insulator is ideal for long-span lines, wind-intensive regions, and distribution networks that demand additional structural stability.

The model is characterized by its strong glass structure, enhanced dielectric strength, and resistance to environmental stresses such as UV radiation and industrial pollution. High creepage distance ensures better performance in humid or slightly polluted environments. Utility companies choose the CTS 120–1 because of its reliability and compatibility with existing hardware configurations.

CTS 120–2P Toughened Glass Insulator (Dual Shed)

A double-petticoat version of CTS 120–1 with increased creepage distance for polluted or coastal regions.

The CTS 120–2P is a specialized dual-shed (double petticoat) toughened glass insulator designed to improve pollution and moisture performance. While it shares the same 120 kN mechanical rating as the CTS 120–1, it features a significantly larger creepage distance, making it ideal for high-pollution areas, coastal regions with salt fog, and industrial zones.

The dual-shed profile ensures superior hydrophobicity retention, better surface flashover resistance, and stable performance under severe weather conditions. As part of its premium product range, Nooa Electric manufactures the CTS 120–2P with high-grade toughened glass for long-term reliability and reduced maintenance.

Strong mechanical reliability, superior dielectric performance, international certifications, and global reference projects.

1. What is the advantage of toughened glass over porcelain insulators?

Toughened glass shatters safely into small pieces upon failure, making defects easy to detect visually. It also offers better dielectric performance and long-term weather resistance.

2. What is the difference between CTS 120–1 and CTS 120–2P?
Both models have 120 kN mechanical strength, but the CTS 120–2P has a dual-shed design, providing increased creepage distance and better performance in polluted or coastal areas.

3. Are CTS models compatible with international standards?
Yes. All CTS insulators from Nooa Electric comply with EN 60383-1 and EN 60305, widely used across Europe and global markets.

4. What voltage levels do these models support?
CTS 70–1: 10–20 kV
CTS 120–1 & CTS 120–2P: 20–35 kV

5. Can Nooa Electric provide OEM and customization services?
Yes. Nooa Electric supports custom creepage distances, metal fittings, markings, and packaging according to client requirements.
