ELECTRICAL GROUNDING BACKFILLS

POWERSET

PERMANENTLY SETTING GROUNDING BACKFILL

LORESCO PowerSet™ is a low-resistivity, hardening ground enhancement backfill for copper grounding systems.

When the specification calls for a hard setting grounding material PowerSet™ is the product of choice. PowerSet™ is compatible with all standard copper grounding systems and standard field applications. It is an economical permanent solution to difficult grounding problems in hard to deal with areas. PowerSet™ is manufactured from environmentally safe materials and is extremely stable. When mixed with water or exposed to moisture, PowerSet™ attains the hardening characteristics of cement while retaining its highly conductive properties. PowerSet™ will remain highly conductive during a drought or when exposed to arctic temperatures. Because is does not have any shrinkage or expansion properties it will remain in constant contact with the earth.

PowerSet™ can be poured in dry or pumped in slurry form. No tamping is required. It is very worker friendly. No special tools are required.

ADVANTAGES

  • 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.

  • Electrically conductive.

  • Environmentally friendly.

  • 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.

To calculate the amount of material required to fill a trench. First, determine your desired thickness of PowerSet™. Second, move to the right until you are under the known width of the trench. This number will be the weight of the material lbs./linear ft. Take this number and multiply by the length of the trench in feet. Your answer will be the amount of PowerSet™ material required to fill the trench to the desired level in lbs.

EXAMPLE

Thickness = 6 inches
Width = 12 inches
Answer = 32.3 lbs/linear ft

32.3 lbs/linear ft x 50 ft of trench = 1615 lbs of PowerSet™

VERTICAL INSTALLATION

  • Drill or dig the earth hole to the desired diameter and depth.

  • Suspend ground rod in center of hole to be filled.

  • Pour PowerSet™ until desired level is obtained.

  • Remove excess water prior to pumping.

  • If necessary, PowerSet™ may be pre-mixed and pumped under water.

HORIZONTAL OR GRID CONSTRUCTION

Entire grounding system should be surrounded by PowerSet™. Conductors should be insulated as they exit the PowerSet™ column. PowerSet™ should be used as a ground enhancement material when a setting fill is specified.

HORIZONTAL CONSTRUCTION

  • Pour into horizontal trench until level of ground wire is reached.

  • Place ground wire. Pour in additional PowerSet™ until ground wire is covered to desired height.

  • Cover with fill. No tamping is necessary.

  • Remove excess water prior to application.

GRID CONSTRUCTION

  • Pour PowerSet™ 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 PowerSet™ around the grounding system will reduce surge impedance by increasing the effective contact area of the electrode to the soil.
