IEC 61111 Electrical Rubber Mat for Substations | Duratuf Products
Substations carry some of the highest voltages on an electrical network, which is exactly why insulating rubber mats are a standard part of substation safety equipment almost everywhere in the world. This blog looks specifically at what IEC 61111 covers, why it matters for substation work, and how to select the right mat for a substation environment. Why substations need a dedicated insulating mat standard ? A substation floor puts personnel close to live bus - bars, transformers, and switchboard , often at voltages well above what other industrial areas handle. A general-purpose rubber mat with no electrical rating offers no protection here. IEC 61111:2009 exists to define exactly how much voltage a mat can withstand, how it is tested, and how it must be constructed, so that a mat specified for a given substation voltage actually performs when it matters. What IEC 61111 actually tests ? The standard defines mats across five voltage classes 0 to 4 and specifies thre...
