Low-loss and interference-free
KUVAG insulation products for reliable power grids
Transmission networks at the high-voltage and extra-high-voltage levels represent the backbone of our energy supply. They enable comparatively low-loss electricity transmission over long distances. The strong trend towards renewable energy from wind and hydropower and the continuously growing global energy demand mean that there is now a need for improved solutions and innovative concepts.
The objective is always interference-free operation over decades. Therefore, we at KUVAG are continuously optimizing our insulation products, which are used in all areas of power transmission and distribution networks. A particular focus is placed on components and systems for transmission grid nodes, such as high-voltage and extra-high-voltage switchgear, circuit breakers, transformers, and cable systems. Our experts support manufacturers of these systems in the design and development of specific and innovative insulation solutions.
Switchgear
Switchgear for high-voltage and extra-high-voltage applications in combination with transformers are crucial key components in substations. KUVAG produces both insulators for air-insulated switchgear (AIS) and more compact gas-insulated switchgear (GIS), where sulfur hexafluoride or alternative gas mixtures are used as the insulating gas.
KUVAG is the world’s leading independent manufacturer of insulators for these applications. We develop and manufacture specialized insulation products for GIS, AIS, circuit breakers, disconnectors, current and voltage transformers, busbars, and supports. Our product range includes epoxy resin encapsulated components like bulkhead insulators to cable terminators, composite switchgear, and silicone-sheathed GRP composite insulators. Numerous well-known switchgear manufacturers rely on our high-quality materials and leading technology, which enable an expected service life of over 40 years. We have decades of experience and proven expertise in insulator design, engineering, and manufacturing and can successfully deploy these critical components in demanding environments and applications.
Cable accessories
Operationally safe power grids require safe and permanent connection of switchgear and transformers to overhead lines or cables. KUVAG develops and manufactures components for cable accessories of the highest quality. Our most important criteria are installation that is as uncomplicated as possible, high reliability over decades of use, and resistance to water and corrosion.
KUVAG is the leading provider of components for cable fittings and has decades of experience in the development, design, and manufacture of epoxy resin insulators for cable terminations and silicone-sheathed glass fiber reinforced composite- hollow core insulators for outdoor cable terminations. We collaborate with the leading manufacturers in this sector and have excellent knowledge of materials, design, and manufacturing technologies. Our uniquely broad product range makes us the ideal partner for our customers. We offer insulation technology from a single source.
Overhead lines
Overhead lines are used for interregional electricity transmission and local distribution and may well be called the lifelines of society. Insulators of the highest quality are required to guarantee extended durability and reliability. KUVAG composite insulators fulfill exactly these requirements.
Composite insulators have been gaining importance over ceramics and glass in recent years. KUVAG composite insulators combine the findings of many years of research in the fields of insulating materials, GRP rods, end fittings, crimping technology and injection molding. Our products feature high mechanical strength, resistance to erosion and tracking, and outstanding hydrophobicity, even in highly loaded environments. Depending on the insulator’s specific application, we use HTV (high temperature vulcanized) silicones or LSR (liquid silicone rubber).
Inspection and test equipment
Effective high-voltage testing and measurement systems are indispensable for testing transformers, cables, switchgear, and other key network components. They generally involve very high test voltages, sometimes in the range of over 1 MV. High-quality insulation components from KUVAG are optimized for use in such systems.
Numerous well-known manufacturers rely on KUVAG quality for the design and manufacture of their large-scale testing systems. These systems are mostly developed according to customer-specific test requirements, which necessitate tailor-made solutions regarding the insulation components. Our many years of experience and wide range of products make us the ideal partner even for challenging applications. Quality without compromise – our customers appreciate this KUVAG commitment.
