Electrical insulation materials
Tenmat offers several solutions for high-temperature applications within the chemical and energy industry. Tenmat materials, components and products are used as arc chutes within air break circuit breakers in power generation, mechanical seals in pumps or in heat and electrical insulation applications.
ELECTRICAL INSULATION MATERIALS
High-temperature mechanical seals
A mechanical seal consists of two extremely flat faces running against each other, one fixed and one rotating. The seal faces are pushed together using a combination of hydraulic force from the sealed fluid and spring force from the seal design. In this way, a seal is formed to prevent process fluid from leaking between the rotating and stationary areas of the pump.
Material selection for seal face combinations
Various materials can be chosen for the seal face combination. Generally, this comprises two, non-identical materials. Depending on the application and the fluids being sealed, the design engineer has to choose the most appropriate material combination.
Nitrasil engineering ceramics
Nitrasil is an engineering ceramic with superb inert properties that allow applications in numerous high-temperature and non-ferrous molten metal environments
ELECTRICAL INSULATION MATERIALS
Switch gear
A tried and trusted method for controlling high-power electrical switching is the air break circuit breaker. Such breakers incorporate Arc Chutes to extinguish electrical arcs and these Arc Chutes need materials that are proven to withstand extremes of electrical and thermal environments, for decades and decades. Around the world from Nuclear Power Stations to high-speed train systems, Tenmat materials are integral in controlling electrical arcs.
Health and safety: upgrading historical breakers
Equipment designed and built in the mid and latter part of the last century uses air break circuit breakers. The design is so good that the breakers have decades of use ahead of them but some still contain asbestos cement. Tenmat offers a solution to those companies who wish to retain the original air break circuit breakers but remove the asbestos cement. Refurbishment is a much more cost-effective solution than new equipment. Health and safety issues become a problem of the past.
