ATPV 100 CAL/cm2 fall into category HRC 4 arc flash protection.

Medium voltage applications with very high electrical energy levels.

APTV 100 CAL/cm2 ARC Flashsuits are used in high energy applications, where higher voltages occur with higher fault levels are experienced. The 100 CAL suit provides greater protection from the heat generated electrical ARC’s generated from. ( Voltages such as 6.6kv , 11kv , 24kv , 36kv)

ATPV values – the higher the value, the more insulated one is from second degree burn.

HAF – Heat Attenuation Factor. The higher the HAF%, the more the heat is blocked by the fabric.

The more layers the fabric has ( layers) the greater the protection from shrapnel.

Arc flashes occur when electricity jumps across the phases and cause a short circuit and subsequent flash. Arc flash occurrences are a factor of the distance between the phases and distance from the source ( transformer) , the circuit breakers trip time, the available short circuit current, dirt buildup in the equipment which may affect the conductive path, moisture (humidity), circuit supply voltage, amount of motor contribution during a fault, indoor versus outdoor applications and the distance of the operator from the switchgear.

Applications with medium voltages and medium fault levels have significant energy levels. Electricians working on distribution boards in various factories, mining and substations with medium voltage applications are at risk from arc flash occurrences. Medium voltages have the necessary potential to jump across phases, when these do occur the arc flash can be just as severe and harmful a higher voltages when the conditions allow.

To provide adequate protection, the electrician should be protected from head to toe. The APTV 100 CAL headkit has a tinted visor that protects from thermal effects, conductor shrapnel and blinding light generated from the arc. APTV 100 CAL Jackets and trousers are available in only two piece. APTV 100 CAL Gloves are designed to provide maximum dexterity so that the electrician’s work is not inhibited. 20000v boots provide the insulation for live work conditions and a bag holds all the equipment together.
