What category of insulation is offered by RH Aerial Lift Equipment?

C Category
What is the difference between the A, B and C category of insulation you would ask me?

The C category units have a coverage of a maximal voltage of 46 kV and lesser. The dielectric parts of the unit supplies only a secondary protection to the operator in the bucket meaning that is the insulation stops/begins where the fiberglass starts or ends.

RH Aerial Lift Equipment provides a 4-foot fiberglass (yellow) section, which allows the unit to be insulated in all position. It is located between the basket (bucket) and the aluminum section. Only the ground crew will be protected. The main coverage (primary) is intended to be supplied by other means such as: rubber gloves, appropriate insulated clothing, hot stick, etc.


A and B Category

The A and B category are designed to supply the main protection to the operator in the bucket beside the crew that surrounds the user.  They are provided with means to control the potential electric leak with an insulating aerial device (periodic electrodes system). The unit of a C category does not require this system and that is what makes the difference.

** For informational purposes, all the dielectric units from RH Aerial Lift Equipment Inc. beforehand filled the dielectric technical clearance (qualification) of a “C” category regulation according to CSA standards; C225-10 CSA and C225-00 CSA. This test last 3 minutes using 100 kV, 60 Hz and the electric leak does not exceed 1 mA. **
