Performance Standard: DL/T879 -2004 portable earthing and earthing short circuit equipment for live workingï¼?
Material requirements: high purity copper wire, copper purityâ?¥99.999% .
Technical parameters: the grounding wire is made of many strands of soft copper wire, the diameter of the single wire is not more than 0.2 mm, and the surface is covered with transparent insulating layer (including the grounding wire, where it is connected with the end clamp of the grounding wire) , the thickness of the protective layer is not more than 1.5 mm.
The installation of the terminal adopts the secondary drawing process. The transparent sheath of the grounding line is installed in the pipe and the spring is added to form the secondary protection, therefore, the copper wire can not be broken during the use, and the transparent heat-shrinkable tube is used for the terminal sheath to observe whether the ground wire has been broken or not.
Earthing System is very essential to be properly designed & installed to safeguard both lives & the equipment. Sometimes it happens that though the earthing system is installed, current leakage is felt & short circuit may happen. To avoid this a correct Earthing System embracing correct earthing accessories is very important to take care of. Corrosion resistance, conductivity and mechanical strength are essential considerations in earthing accessory design to ensure an earthing system remains operative for many years. All AMPL Earthing Accessories have high quality copper alloy material which provide wanted strength to the part to ensure its proper mechanism. Material: Brass - Gunmetal - Bronze - copper - SS - are main metals used in manufacturing the equipments in the form of clamps, nut bolts. Sizes & Types: Rain Water Pipe Bond, Jointing Clamp, B-Bond, Tee-Clamp, U Bolt Rod to Cable Clamp, Tower Bond Clamp, U Bolt Rod to Cable Clamp, U Bolt Rod to Cable Clamp, U Bolt Rod Clamp, Rod to Cable Lug Clamp. Finish: Natural, Nickel, Tin or any coating as per custom specification.
Copper ore is a naturally occurring mineral rock that contains copper in varying concentrations. It's extracted from the earth through mining and then processed to produce copper concentrate, which is further refined to produce pure copper.
## Types of Copper Ore
1. Sulfide ores: These ores contain copper in the form of sulfide minerals, such as chalcopyrite (CuFeS2), bornite (Cu5FeS4), and chalcocite (Cu2S).
2. Oxide ores: These ores contain copper in the form of oxide minerals, such as cuprite (Cu2O), tenorite (CuO), and malachite (Cu2CO3(OH)2).
3. Native copper: This type of ore contains copper in its native form, often found in quartz veins or other igneous rocks.
## Copper Ore Deposits
1. Porphpyry copper deposits: These deposits are formed through magmatic-hydrothermal processes and are characterized by large, low-grade copper deposits.
2. Volcanogenic massive sulfide (VMS) deposits: These deposits are formed through volcanic activity and are characterized by high-grade copper deposits.
3. Sedimentary copper deposits: These deposits are formed through sedimentary processes and are characterized by low-grade copper deposits.
## Major Copper-Producing Countries
1. Chile: The world's largest copper producer, accounting for approximately 30% of global production.
2. Peru: The second-largest copper producer in South America.
3. Australia: A significant copper producer, with major mines in Western Australia.
4. United States: Copper is mined in several states, including Arizona, Utah, and Montana.
5. China: A major copper producer and consumer, with significant mining and smelting operations.
Uses of Copper Ore
1. Copper production: Copper ore is processed to produce copper concentrate, which is then refined to produce pure copper.
2. Electrical applications: Copper is an excellent conductor of electricity, making it a crucial material for electrical wiring, circuits, and electronic devices.
3. Construction and architecture: Copper is used in building construction, including roofing, plumbing, and electrical systems.
4. Industrial machinery and equipment: Copper is used in the production of various industrial machinery and equipment, including motors, generators, and transformers.

SUMMARY
SNV308.1 series overhead type Fault Indicator system is based on the Sensor that through CT get the (6KV-50KV) lineâ??s current signal, through smart computer chip(IC) by program calculating, Analysis ,judge the short circuit or ground fault. When Sensor detect the fault happen, then the Fault indicator warn the manager through turn red flag, and shine 3 color ultra-led. It is good for power managing user to find the fault happen reason and place, then fast solve the problem and make the power restore.
*SNV308.1 Fault Indicator with the aid of the remote control PDA(SNV306.1), User can read, reset the indicatorâ??s setting parameter, and can read the online real time current etc
*SNV308.1 Fault Indicator with the aid of the professional control terminal equipment(SNV309.1) and Web server, it can achieve to remote read and manage the Fault indicator state on times.
There are two channels for reading and managing the remote fault indicators. One is through GSM mobile phone SMS command control. Second is user computer software control. Power managing user, can get the fault indicator information on times
An Earth Leakage circuit breaker (ELCB) (now referred to as residual current circuit breaker-RCCB) is a safety device used in electrical installation with high earth impedance to prevent shock.
