Elpress Deep Earthing System

Product overview

The Elpress Deep Earthing System consists of five parts:

  • Hardened Steel Tip
  • Leading Rod
  • Extensions Rods
  • Driving Studs or Sleeves
  • Earthing Wire (supplied by wholesalers)

The Power Hammer required to drive down studs (or sleeves) is registered as a separate product: Elpress Power Hammer for Deep Earthing System.

SIMPLE FUNCTION

The earthing wire is inserted into and held by the steel tip. The extension rods have guiding pins to enter into the previous tube end to form a stable extension of the system. By monitoring the earthing resistance, the driving down may be interrupted at best point.

EARTHING

An earth electrode is a conductor placed in the soil with the purpose to discharge electrical current from a connected facility. The use of electricity with bad earthing includes a high risk. All suppliers of power must have approved earth electrodes at their facilities. It means that flash-over voltages, which can appear for different reasons are led into the soil so they do not cause any damages and/ or injuries. Earthing serves as, among other things, person protection, property protections, Electro Magnetic Pulses protection, lightning protection and similar.

PRINCIPAL DESIGN

The Elpress Deep Earthing concept is a system without extra connection points. The earthing electrode is a copper wire which is pulled down by means of 0.8 m steel tubes (“rods”). A hardened steel tip locks the Cu wire into the leading rod. For each extension rod the wire is pulled a further 0.8 m down alongside the rods. As the earthing resistance may be continuously monitored at the other end of the wire, the driving down is interrupted when a satisfactory low resistance is reached. The top extension rod is pulled up and re used. The driving down is normally made by a Power Hammer for Deep Earthing with a suitable driving stud or with a sledge hammer and the driving cap FS61 or FS62C.
