Maintenance

6.  Maintenance

In order to off er an outdoor solution, 

Ormazabal

's cubicles 

are fi tted with a galvanised sheet metal enclosure painted 

in RAL 7035 polyester powder for outdoors, with corrosion 

category C5, according to Standard ISO 12944-2, and 

high durability (H), according to standard ISO 12944-1. It 

is important to stress that, as indicated in this Standard, 

durability is not a warranty period, but rather a technical 

consideration that helps establish a maintenance period. 

For other categories of corrosiveness and/or durability, 

please contact 

Ormazabal

's Technical Department.

6.1.  Maintenance and cleaning

6.1.1.  General aspects

The switchgear's cleaning and maintenance frequency 

depends to a large extent on the location of the facility. Due 

to their knowledge of the installation, maintenance staff  

are the most qualifi ed to establish time intervals between 

maintenance operations. 

Standard ISO 12944 must be consulted as a reference 

to establish the maintenance periods.
