RONIS of France has made operating in electrical power stations less hazardous, thanks to its new range of interlock systems, specifically designed to ensure the users’ safety while working on medium and high-voltage installations
This extensive range is organised into four product families and offers a large number of locks that can be adapted to any hazardous component by requiring manipulation in a specific order. These systems can be tailored to companies’ specific needs.
From locking isolator controls to access locks (such as flaps, doors and covers), including locking systems for circuit-breaker switches, inverters or transformers, the interlock range by Ronis was specifically designed for maximum safety.
“Each hazardous component is protected by one or more locks, each of which can only be opened with its own specific key,” says a spokesman for the company. “A key will not be available to open a given lock if the preceding lock was not correctly released, making the locks interdependent. This system is the most secure because the locks are mechanical. Every operation is carefully integrated into a full process, where the use of the keys prevents any infringement of the required procedure and eliminates any risk of error.”
These systems are made entirely of metal, using high-quality and durable materials.
A new key centre supplements this already very extensive range. The ELC board makes it possible to activate and release one or more keys by introducing them sequentially, requiring them to be manipulated in a specific order. Equipped with at least seven cylinders, the new ELC board is available in three models (seven to 12 cylinders, 13 to 18 cylinders, 19 to 24 cylinders).
