The protection provided from Du Pont Nomex Arc Flash suites gives a person the benefit
of a few seconds to escape the Arc flash, by preventing the burning of skin. The main
characteristic of Nomex material is to self extinguish.
( FR – Inherently flame retardant – not treated).

A real life saver

Live Line Technology  , Arc flash suits are light-weight , inherently flame Retardent and will save a persons life against an arc flash.

Head to toe protection

The electrician should always wear total body protection from head to toe, including – Jacket, Trouser, Hood, Glove in a Bag.

Caring for your garments

Arc flash suits , need to be carefully cleaned. Do not use detergents and excessive hot water when cleaning arc suits. Store them safely in a bag which is provided by Live Line Technology.

DuPont™ Nomex® fibre is inherently flame-resistant

DuPont™ Nomex®  fibre is inherently flame-resistant, will not melt or drip, and does not support combustion in the air, thus providing excellent arc flash protection. And because the protection is woven right into Nomex® garments, it cannot wear off of wash out over time.

When exposed to the intense heat typical of electric arc, Nomex® fibre carbonises and thickens. This increases the protective barrier between the heat source and the wearer’s skin and helps minimise burn injury.

Nomex Arc flash suites should always be worn when operating high voltage systems for example 11kv, 22kv or 33kv systems in applications such as switchgear inside Substations. (eg. 132kv/11kv) This is to protect against the potential hazard of an arc flash.

The correct arc flash risk assessment needs to be carried out before an ATPV – Arc Thermal Performance value can be determined. The greater the ATPV value.

LLT Save Arc flash ratings :

An electrical arc flash is more severe with higher voltages & higher fault level ratings of the equipment (switchgear) substation. The greater the flash, the greater the severity of the radiation exposed to the operator.  It is imperative to get the correct grading of the Nomex Flash suite to ensure the necessary protection against radiation of the Arc flash.

LLT Save Arc Thermal Performance values (ATPV) :

• 12+ CAL. (Conti)
• 21+ CAL (Conti )
• 25+ CAL. (Conti)
• 55+ CAL Arc
• 65+ CAL.
• 100 + CAL.
• 140 + CAL.

Arc Thermal Performance value (ATPV value) is presented in calories per centimeter square and represents the maximum capability possible from an arc flash protection for particular clothing.

Characteristics of Arc fabric :

Absorbs Heat Energy

The fiber itself absorbs heat energy during the carbonization process.

Eliminate Air Movement and Heat Transfer

The fibers eliminate air movement and heat transfer to the interior skin area.

Insulating Barrier

An insulating barrier reduces heat transfer to the person.
