Who we are?

The protection of people and equipment is our passion. Our Technology is “Live Line”. We want to keep the operators alive, when operating with live equipment.

How does an Arc occur?

Arc Flash suits are a small cost in comparison to the loss in quality of life if a worker is exposed to an electric arc event.

What causes Arc Flashes?

Arc flash is a short circuit through air that flashes over from one exposed live conductor to another conductor or to ground.

Components of a typical Arc Flash Suit

APTV 8 CAL – 140 CAL

Live Line Technology Arc flash suits provide full body protection.

LLT Arc Save Flash suit consists of the following products – ARC Flash Hood, ARC Flash Jacket, ARC Trousers, ARC Flash gloves and protective boots.

The ARC Flash categories range from as 12 CAL to 140 CAL, and a wide variety of clothing ranges such as ARC Flash undergarments, ARC flash casual wear.

Function of NOMEX Arc Flash Suits:

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

Sizes:

Small – 5XL (prices do vary according to size).

Colour:

Olive, Black , Navy blue , Orange

Material:

Blended 33% Nomex/Kevlar, 66% Modacruylic & 2% Antistatic liners.

TRIPLE LAYER
ATPV¹ range : from 12 cal/cm to 140 cal/cm²
Specification : ASTM F1959/ 1959M ASTM F1506; NFPA 70E;
SANS 724.

Arc Flash Suits vs Polly/Cotton fabric:

Our flash suits provide significantly better protection than the usual clothing fabric not just during an arc flash explosion but also afterwards as the suit will not be set on fire.

Application:

Personal protective switching suit designed for the electrical industry to withstand the thermal effects of an electric arc flash.

Characteristics of NOMEX fabric:

The fiber itself absorbs heat energy during the carbonization process.

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

An insulating barrier reduces heat transfer to the person.

International Standards :

SANS 724, ASTM 1506, OSHA 1910.269

ASTM 1959 F1959/1959M

Features:

  • Light weight.
  • Material: Multi-layer DuPont™ Nomex® / DuPont™ Kevlar® / Modacrylic
  • Guaranteed flame resistant for the life of the garment.
  • Machine washable.
  • Excellent breathability.
  • Cool cotton comfort.
  • Arc Flash Jacket designed to interface with Arc Flash Hood.

Arc Flash Suits 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 flash ratingsl:

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)
  • 16 – 20+ CAL (Conti )
  • 25+ CAL.
  • 55+ CAL Arc & Oil
  • 74+ 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.
