Duval Messien earthing systems accessories are designed for installing an earthing system to flow the lightning current to the earth. 

EARTH RODS 

PIQACUA1M earth rod in copper coated with a diameter of 17mm is made with semi-hard steel « soul » which rigidify the earth rod and coated with 350 µ copper by lining after adhesion treatment.

The tip allows a coupling earth rod to earth rod without any other accessories (self extensible earth rod).

To drive into the ground the earth rod without damaging technical and functional components, it is recommended using a driving head (GUIDFRAPIQ2) and a driving stud (GUIDGOUJON2), avoiding any damages on earth rod head.

This system allows to keep a permanent diameter on the whole length of the rod, to ensure a better contact with earth and to get more mechanical resistance.

The tip, in hardened steel, screwed at the end of the 1st earth rod allows the driving in, even with hard grounds.

PIQINOX1M earth rod in stainless steel with a diameter of 16mm, is extensible by element, each extremity is M10 threaded which allow to adapt by clamping the GOUJONIN10 connection screw. It is recommended to use GUIDGOUJON to avoid to damage the earth rod head. The 1st earth rod to install should be equipped with a tip POINTEACSP.

A CONPIQRUB2 clamp is installed on the head of the earth rod and allows the connection betwwen the tape and the earth rod.

ACCESSORIES FOR EARTH RODS

EARTH GRIDS 

GRILTER1/1 and GRILTER2/1  earth grids are constituted of a metallical lattice welded in bare copper with meshes with dimension 115 x 30 x 30 mm. They are designed for installing horizontal earthing systems on hard grounds.

INSPECTION PITS

ACCESSORIES

PLAQDMTEROR2 lightning earthing systems are designed for tracking earthing system and can be used as warning system (prevention against risks of pace voltage and contact voltage).

BAREQUI100 or BAREQUI150 equipotential bars are designed for doing an interconnection, easily accessible with the electrical network of the building. It can also be used as control junction.

SERBARLAI named also cable brass dip is designed for connecting 3 to 4 flat conductors between each other.

SELFTER ground coil is installed in serie on the equipotential bonding of two earthing systems, as close as possible to the earth of the masses (inspection pit or at the bottom of a wall).

GROUND TESTER

MDM20K ground tester is designed for an easy and fast measure of the earth resistance and ground resistivity. This pack includes all the necessary pieces for its use (reels, earth rods, decametre..)

 GROUND IMPROVING

TEREC+ allows to realize earthing systems with low resistance.
