"Electric arc is a complex phenomenon"<br />
• Open air arc - The most widely understood<br />
• Arc-in-a-box - Used as a method of testing Arc<br />
garments in the EU<br />
• Ejected Arc – projectile arc plasma<br />
• A tracking arc - Most common at higher voltages,<br />
arc plasma conducts on skin or through clothing<br />
In lab testing, we control movement of the arc for the sake<br />
of replication, but in reality, from 480V higher, the openair<br />
arc can quickly turn into an ejected arc or a tracking<br />
arc.<br />
Creating workwear that can protect against arc exposure<br />
has meant working closely with fabric manufactures and<br />
wearers as we sought to understand how we can mitigate<br />
this hazard whilst not compromising on comfort. In doing<br />
so we have design our Tecwear Arc Protect clothing<br />
range to be able to withstand extreme temperatures of up<br />
to 12,000°C, explosive forces, emission of plasma, fast<br />
moving debris and hot liquids.”<br />
To ensure that our Tecwear Arc Protect coveralls,<br />
jackets, trousers and base layers meet British and<br />
European safety standards we manufacture these<br />
garments under Article 11b and subject all our Arc<br />
protection garments to strict BTTG testing and<br />
certification. This means Tecwear Arc protection<br />
garments are accredited and conform to the latest IEC<br />
61482 – Protective Clothing against Thermal Hazards of<br />
Electric Arc, adding that much needed peace of mind.<br />
