The ACER VOLTAGE Ltd. company was founded in 1992 in Hradec Kralove, originally called ACER. It is a purely Czech company which is engaged in the development and production of surge arresters and overvoltage limiters for the protection of LV and HV power distribution networks, and to protect various equipment against lightning and switching overvoltage faults. Furthemore, it also focuses on the production of composite insulators.Products of ACER VOLTAGE company protect their buyers' equipment from the devastating effects of surges.

The company has been functioned since 2006 under the name ACER HK Ltd., and at the end of 2014 it relocated to a new area, where it remains to this day. 

In 2016, the company renamed to its current name ACER VOLTAGE Ltd. that better reflects its focus and activities.
In the past, the company developed and manufactured ZnO varistors for surge arresters in the LV applications, and then another type of surge arresters made of these varistots. The first type was the surge arrester SP 0.440 / 10, which has been improved, and is now produced only in the SPB * / 10 design in various voltage levels depending on the type of installation. the production of ZnO varistors was abolished in 2006, and currently we use in surge arresters only varistors from external suppliers. Another significant part of our production program are polymeric arresters for both AC and DC 1-39 kV HV networks . They consist of an entire range of models, which is constantly expanding. In addition, it is possible to produce nonstandard types according to customer requirements and specifications.
