Positive low resistance, electrical connection to the earth.
Compatible with all copper grounding systems.
Does not contain any hazardous chemicals.
Will attain a hardened state.
Will not leech into the ground or wash away.
Never needs recharging.
Stable permanent ground for the life of the grounding system.
Contains a corrosion inhibitor to protect copper.
Will not expand or experience any shrinkage.
Not affected by freezing.
Simple to install.
Excellent shelf life with no performance effects.
Horizontal or Grid Construction: Entire grounding system should be surrounded by PowerSetTM. Conductors should be insulated as they exit the PowerSetTM column. PowerSetTM should be used as a ground enhancement material when a setting fill is specified.
Pour into horizontal trench until level of ground wire is reached.
Place ground wire. Pour in additional PowerSetTM until ground wire is covered to desired height.
Cover with fill. No tamping is necessary.
Remove excess water prior to application.
Pour PowerSetTM and spread over ground until desired thickness is achieved.
Cover with fill.
Use ground staples to maintain ground wire in center of fill.
The use of PowerSetTM around the grounding system will reduce surge impedance by increasing the effective contact area of the electrode to the soil.
Loresco DW-1® may be poured freely into dry applications. Tamping is not required. When it is applied by pumping, the recommended method is to pump from the bottom of the bored hole upward. After the application pipe (a one-inch steel pipe) is lowered down to the bottom of the bored hole, it is coupled to a 20 GPM pump with a minimum capacity of 250 psi. Normally, the application pipe does not have to be raised during pumping procedures.
Horizontal Installation Procedure:
Have a reasonably clean ditch (design usually calls for a ditch one foot wide).
Pour Loresco DW-1® in a continuous layer six inches deep (or as specified).
Place anodes on top of DW-1®.
Pour DW-1® in a continuous layer six inches deep until anodes are covered by a six inch backfill cover (or as specified).
Fill the remainder of the ditch as specified.
Vertical Installation Procedure
Have a reasonably clean hole (depth depending on soil resistivity).
Place one foot of DW-1® in bottom of hole.
Lower and center anode in proper position.
Pour DW-1® over anode until design level is reached.
Fill remainder of hole as design specifies.
Bulk density: 74 lbs. per cubic foot.
Particle sizing ranging from 0.1 to 1 mm.
Loresco DW-1® is shipped in fifty (50) pound (22.7 kg) coated, woven polypropylene bags. DW-1® may be stored outside for limited periods (not to exceed four hundred hours of sunlight). Pallets are available with fifty bags per pallet. Proven export packaging is also available.
Loresco SC-3®, due to its dust-free manufacture, is simple to install by either mixing and pumping or by pouring. With deep anode systems, pumping from the bottom up is recommended. Loresco SC-3® has superb pumping qualities due to the addition of surfactants and when agitated in water, takes on the characteristics of heavy mud. A recommended mix is seven gallons of water per one hundred pounds. After installing SC-3®, allow twenty-four hours settling time before energizing. The modified surface of the carbon particles coupled with the action of the surfactants in SC-3® will achieve positive electrical contact by settling. Vibrating or compacting is not necessary.
Loresco SC-3® is a surface modified, blended, and sized carbon backfill with surfactants.
Bulk Density: 74 lbs. per cubic foot
Predominantly round particles
All particles surface modified for maximum electrical conductivity
Particle Sizing: To be dust free with a maximum particle size of 1 mm
Minimum calcination temperature of base materials is 1250° C
Base materials are calcined under ISO 9002 quality control
Surfactants are added to assist pumping and settling
No de-dusting oils are used during the manufacture of base particles
