High-Performance MV Insulators (Composite & Porcelain)
Insulators are the frontline defense against electrical flashovers and leakage currents. Adamiano manufactures both **Polymer (Composite)** and **Porcelain** MV Insulators, providing tailored solutions to meet the specific requirements of India’s varying atmospheric conditions, from coastal saline environments to heavy industrial pollution zones.
Our products are designed for superior performance across **11kV, 22kV, and 33kV** lines, ensuring maximum leakage distance and reliable flashover performance required by major utilities and infrastructure projects.
Primary MV Insulator Types
Composite (Polymer) Insulators
Engineered for superior performance in polluted areas, our Polymer Insulators feature a fiberglass rod core and weather-sheds made of high-grade **Silicone Rubber**. Their key benefits include high durability, lightweight construction, and **hydrophobic properties** that dramatically reduce the risk of tracking and flashover in humid or contaminated environments.
- **Types:** Composite Pin, Suspension, and Post Insulators.
- **Core Material:** High-strength, corrosion-resistant ECR-glass fibre rod.
- **Application:** Ideal for tension and suspension lines in highly polluted or remote areas.
Porcelain Insulators
The traditional and trusted choice for power infrastructure, Adamiano’s Porcelain Insulators offer exceptional **mechanical strength** and long service life. Manufactured from high-quality alumina, they are glazed for non-porous perfection and utilized where robust mechanical performance is paramount.
- **Types:** Porcelain Pin Type, Disc Type, and Shackle Insulators.
- **Mechanical Strength:** Excellent resistance to high tensile and cantilever loads.
- **Application:** Widely used by utility boards, railway electrification, and industrial facilities.
Technical Compliance and Quality Assurance
Choosing the right insulator requires detailed technical compliance. All Adamiano MV Insulators undergo rigorous testing to guarantee they meet or exceed safety and performance benchmarks.
- **Standards:** Fully compliant with **IEC 60383**, **IEC 61109** (Composite), and relevant **BIS** standards.
- **Critical Ratings:** Guaranteed performance for **SML (Specified Mechanical Load)** and **BIL (Basic Impulse Level)** for respective voltage classes.
- **Testing:** Includes Dielectric Withstand, Mechanical Failing Load, and Tracking & Erosion Tests.

Frequently Asked Questions (FAQs)
Q: Should I choose Polymer or Porcelain insulators for a coastal area?
A: For coastal (saline) areas, Composite (Polymer) Insulators are generally recommended. Their silicone rubber sheds have natural hydrophobicity, meaning moisture runs off, preventing the formation of conductive layers common in polluted environments.
Q: What standards do your MV Insulators comply with?
A: All our MV Insulators are rigorously tested and certified to comply with relevant Indian Standards (BIS) and International Electrotechnical Commission (IEC) specifications, ensuring maximum safety and reliable performance.
