For over 30 years, Balmoral Engineering have been supplying electrical insulation mats, barriers and pipes. Over this time, there have been considerable improvements in material technology. This has been especially prevalent in the rubber industry.
With rubber being the choice of materials for electrical insulating purposes, there are still many options to choose from when it comes to rubber products. Ultimately, the final application and environment should determine the suitability of the various rubber options.
Synthetic rubbers have advanced a long way with various hybrids being developed to combine the best characteristics of different compounds.
Balmoral Engineering, after much research and development, have found that EPDM rubber is suitable for the electrical insulation application. This application typically involves mats either being rolled and stored on trucks as a portable insulation barrier, or longer lengths being used in a more static fashion in front of switchboards at substations.
The characteristics of EPDM rubber that make it favourable to these applications include its resilience and toughness to ozone, UV and general weathering. It is also a relatively light weight rubber, making it suitable for portable applications.
The EPDM rubber possesses good physical properties such as tensile strength and puncture resistance. It also has good electrical insulation properties. The EPDM manufactured by Balmoral Engineering is also a high grade EPDM with a good degree of flexibility, making it suitable for rolling and storing in this manner.
Balmoral Engineering’s EPDM is finished with a cloth exterior, which has a non-slip surface even in wet conditions. EPDM has a good temperature range and is typically suitable in conditions from -45° C through to 125° C.
Balmoral Engineering’s EPDM rubber complies with the relevant electrical standards, AS-2978 and is manufactured specifically for the electrical industry.
