Incorporated in the year 2014 at Jaipur (Rajasthan, India), we “3 E Solutions” are the distinguished manufacturer of a wide assortment of Earthing Electrode, Cable Tray, Back Fill Compound and many more.
hemical Earthing is an alternative to conventional Salt Charcoal process, where and earth electrode is inserted in an augur hole in ground and is encapsulated in low resitivity moisture retaining compound. The salt Charcoal is avoided due to the corrosive property of Salt which leaches out with time worsening the performance of earthing.
What are its characteristics?
Conventionally, Gel Earthing is characterized as below : 1. Length : Most important parameter that help to reduce the earth resistance. The Earth Resistance lower linearly with the increase in the length of electrode. 2. Diameter : Generally speaking, increasing the Earth Electrode dia lowers the Earth Resistance, it is more effective to increase the length than increase the dia. It is because the dia of interfering hemisphere remains almost same. 3. Terminal : To connectr the earthing from equipment 4. Materials : The material determine the life of equipment. The better the galvinising thickness, pipe thickness, the better is life.
Premium V/s Normal Earthing
1. Premium Earthing : To satisfy the electrical needs and life of the equipment we manufacture premium earthing in Hot Dip Galvanised Tata Pipes. The hot dip galvanised Tata pipes has best resistance against corroison and hence maximum life in hostile earth environment. Apart from this, the thickness we use is 3.1 mm which has maximum life. Apart from this, the premium earthing is manufactured with Pipe in Pipe Technology. The size of inner conductor is 20 mm i.e. 20 mm Copper pipe in Copper and 20 mm GI pipe in GI earthing. The length of earthing is a variable parameter the consultant choose depending upon the desired electrical properties i.e. Earthing Reistance. It will not be out of place to mention here that Earthing Resistance depends primarily on Soil Conditions ( Electrolyttic properties of soil, compactness and in turn on Soil Resistivity ).
The Terminal sizes are standard, i.e. for 80 mm Dia earthings 50X 6 mm and 50 mm Dia earthing 40X 5 mm in Copper or GI both.
2 Normal ( Economic ) Earthing : Here the thickness of the pipes are approx 1.8 mm to 2 mm. The parameters are more or less same except the pipe thickness and inner conductor. The inner conductor is in Strip in Pipe technology i.e. 25X3 mm in GI and 20X2 mm copper in Copper earthings.
Cable Trays are used as support for laying Power or LT Cables. Two types of Cable trays are in frequent use:
1. Ladder Type Cable Trays 2. Perforated Cable Trays
Ladder Type Cable Trays :
Generally used in applications with intermediate to long support spans 12 to 30 feet.A ladder cable tray without covers permits the maximum free flow of air across the cables. This allows the heat produced in the cable’s conductors to effectively dissipate. Under such conditions, the conductor insulation in the cables of a properly designed cable tray wiring system will not exceed its maximum operating temperature.
The rungs of the ladder cable trays provide convenient anchors for tying down the cables in the non-horizontal cable tray runs or where the positions of the cables must be maintained in the horizontal cable tray runs. This capability is a must for single conductor cable installations. Under fault conditions (short circuit), the magnetic forces produced by the fault current will force the single conductor cables from the cable tray if they are not securely anchored to the cable tray. Cables may exit or enter the ladder cable trays through the top or the bottom of the cable tray. Where the cables enter or exit conduit, the conduit to cable tray clamps may be installed upright or inverted to terminate conduits on the top or bottom of the cable tray side rail. The most common rung spacing for ladder cable tray is 9 inches. This spacing may be used to support all sizes of cables.
Perforated Cable Trays:
These are the most common t ype of cable trays available in market. GI perforated Cable Trays in GP is common whereas the other type, in Hot Dip Galvanised or Powder Coated Cable trays are supplied against order only.
The follwoing are common sizes 1.6 mm thickness - 50X40 mm 1.6 mm thickness - 100X40 mm 1.6 mm thickness - 150X40 mm 1.6 mm thickness - 200X50 mm 1.6 mm thickness - 250X50 mm 1.6 mm thickness - 300X40 mm
Backfill compound is used surrounding the earth electrodes in Chemical Type earthings. These compounds are not containing corrosive mineral salts in excess of 2 to 5 % though are conductive due to the properties of moisture retention and Calcium or Sodium based montmorillonite compounds. These comes in bags of 22 to 25 kg.
A lightning rod or lightning conductor is a metal rod mounted on a structure and intended to protect the structure from a lightning strike. If lightning hits the structure, it will preferentially strike the rod and be conducted to ground through a wire, instead of passing through the structure, where it could cause electrocution or fire. EUROSTAR active lightning rods are available in the following varieties: EUROSTAR ES. 15 / 30 / 45 / 60 with 15 / 30 / 45 / 60 microseconds action and silver basic color. EUROSTAR lightning rods have been tested in ICMET high voltage laboratory, Craiova, Romania, according to NFC 17-102 standard specifications. ICMET high voltage laboratory is certified to work with European standards
