Electric Actuators Power Plants

Quality Without compromise The SIWI M7636 series is intended for use outside the containment area while the SIWI-AS M7637 series has been designed for inside containment applications. As well as having important additional safety functions, the SIWI-AS actuators are designed to be fault-proof when using design-basis accident analysis criteria, for example LOCA (Loss of Coolant Accidents). Safety is of the utmost importance in nuclear power plants and quality standards cannot be compromised. Recognising this fact, SIPOS actuators have been designed specifically for use in the nuclear...

Refined technology Down to the finest detail Reliability and quality that focuses on the fine detail characterises SIPOS’ actuators. With 50 years knowledge and experience in manufacturing electric actuators for nuclear power plants, SIPOS Aktorik understands how each individual element contributes to the quality of the complete actuator. Every SIWI-AS component is designed to be fault-proof and the user can be confident of the product quality, as every part is individually tested during the production process. SIPOS is proud to highlight the fact that its products have a proven functional...

The right interface For every connection Each actuator is tailored for individual operating environments. Comprehensive customisation ensures long-term system reliability during plant operation. For example, the electrical connections of SIWI-AS actuators have pressure-tight cable entries to provide trouble-free service, capable of withstanding extreme environmental conditions. This ensures that the actuator functions perfectly, even in adverse fault scenarios. Electrical interface SIPOS supplies many different types of connection to ensure interfaces are available for an extremely diverse...

Documented safety Detailed verification additionally stipulates the need for calculative verification records of all components in the mechanical chain (power flow). This involves the determination and verification of the predefined safety factors/service life values of all the components in accordance with recognised calculation methods. Relevant industry norms and standards stipulate strict requirements for the quality of or actuators used in nuclear power plants. Difwer ferent industry standards have varying criteria for the range of operating condiperating or tions in which the actuator...
