SHIPPING 

 
ELECTRO COMPOSITES (2008) ULC bushings are shipped in OSB board (presswood) 
crates, supported at two points.  Bushings are shipped horizontally or exceptionally at 
vertical position. 

 

 

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 

As ELECTRO COMPOSITES (2008) ULC bushings are dry type (no oil or any other fluid 
components within the bushing construction), no special provisions are given for their 
shipping and storage other than given in this guide.  Therefore, they can be stored in 
their shipping crates for an indefinite period of time. 
 
When returning bushings to ELECTRO COMPOSITES (2008) ULC, please use the 
same crating and strapping methods as when they were shipped originally.  Insure you 
have been provided a RMA (Return Material Authorization) number from your Electro 
Composites (2008) ULC representative prior to returning any material back to the 
factory. 
 

RECEIVING 

 
Bushing crates are constructed with provisions for handling with forklift equipment.  
Insure for sufficient support of crate, as weight distribution within the crate is not 
balanced.  Reasonable care should be taken when opening the crate so as not to 
accidentally damage the bushing.  Crates are usually assembled with wood screws.   
 
Inspect crate and bushing(s) carefully for any signs of damage that may have occurred 
during transport.  Visually inspect each bushing for any signs of impact, cracks, loose 
components or abnormal surface conditions. 
 
When opening the crate, take particular care to remove all screws, nails, staples and any 
other sharp metal parts which could damage the bushing or personnel. When using any 
kind of cutting blades, stay clear of the bushing insulation surfaces to prevent damage to 
the insulation.
