NH-Switchgear

Very low temperature can lead to embrittlement of plastics and metals, restrict the functionality of switches and fusegear or make them unsafe. This may even render them inoperable and they can become a safety hazard for operators and surrounding electrical equipment.
Mersen now has developed NH-Switchgear which performs reliably even at extremely low temperatures. It can be used safely under arctic conditions of minus 40 degrees Celsius and offers a number of additional product advantages.
The significant improvements were mainly achieved by increasing the mechanical strength of the NH-Switchgear. It can now be opened, closed and the fuse-links can be replaced at minus 40 degrees Celsius. Special care was taken to make sure that no wear or damage will occur that could potentially cause a malfunction. The Mersen development engineers chose plastics resistant to cold temperatures and optimized highly-stressed sections of the fuse switchgear.
After the finalization of product development and intensive testing the following product groups will be available in the very low temperature resistant version: NH-Fuse-switch-disconnectors MULTIBLOC size 000 / 100A up to size 3 / 630A, NH-Fuse-switch-disconnectors MULTIVERT size 00 / 160A up to size 3 / 630A, NH- Fuse rails BSL size 00 / 160A up to size 3 / 630A.
Also to be launched within the area of power distribution and protection are DIN standard high-voltage fuse-links for switch-fuse combination with less power loss.

Renewables
Furthermore, Mersen provides safety and reliability for electrical power in renewable markets. In solar PV applications HelioProtection solutions by Mersen protect strings and arrays in solar farms producing energy and monitor the production to guarantee long-term power performances. In wind power Mersen markets solutions from the nacelle down to the output to the grid: carbon brushes, brush-holders, power & signal transfer systems and slip ring assemblies for power generation, surge protective devices, cooling of power electronics and bus bars for power distribution. New products in this area are spring terminal fuse-holders and electronic monitoring systems. For the wind power industry, new solutions include a circular bus bar, as well as customized slip ring assemblies.

Mobility
Mersen had been involved in more than 400 transportation projects everywhere and everyday from the 70's. Our expertise is brought to customers in rail, aerospace and electrical vehicles by our experts in traction, power interconnection, electrical protection and thermal management. As market demands for energy efficiency in transportation technology increases, look to Mersen's continued development of reliable and high-performance products means via innovative solutions and services to ensure safety for people and equipment. In Hannover, the company will introduce a new static current collector device for standstill recharging in tramway application.
