SEC Uses Helicopter Mechanized Trimming
Article was added on Wednesday, June 29, 2011
Santee Electric Cooperative Inc. members in the Georgetown,
Hemingway and Carter's areas may have noticed a helicopter flying
close to electric lines with a strange apparatus suspended near the
tree line making a great deal of noise recently.
This helicopter has been performing mechanized trimming to the
rights-of-way near SEC electric lines.
Following standard business practices, SEC uses a bid process to
insure the contractor with the lowest price and best qualifications
is used to maintain the rights-of-way along its 5,458 miles of line
stretching across Florence, Clarendon, Georgetown and Williamsburg
The tree trimming maintenance is done on a five year rotation as
to keep any one area from growing out of control while others are
being worked on.
This year, a large portion of the tree trimming went to
Asplundh, a national company. A smaller portion of the tree
trimming was awarded to a local company, Jimmy's Tree Service.
The mechanized trimming began on March 3 as a result of Asplundh
subcontracting the service to another local company, Rotoblade, of
Salters. Mechanized trimming can cut large areas of line more
quickly and efficiently than traditional trimming. Typically,
Asplundh is able to trim approximately 20-25 spans of primary lines
a day. With the helicopter, they are averaging 80-100 spans of line
a day. This more efficient method of trimming allows Asplundh to be
more efficient which saves everyone involved money.
