PE wire that is, ground wire, is specifically used to ground the exposed conductive part of the electrical device conductor.
PE wire, the full name of the English "Protecting Earthing", Simplified Chinese name is "protective conductor", we live in the "ground" is PE wire. "is PE wire. In our country, the PE wire for the green - yellow two-color line .
In our country, the ground symbol is E, can be divided into power supply ground, circuit ground two kinds.
Expanded information:
PE wire grounding in life is as follows:
1, work grounding.
Work grounding is a metal conductor copper block buried in the soil, and then a point of it with a wire lead out of the ground, with which to complete the circuit so that the equipment to achieve the performance requirements of the grounding line. Ground wire requires grounding resistance ≤ 4 Ω. Such as the 1960s and 1970s rural households use the radio has a ground wire, and in the ground to often wet with water.
2, safety grounding.
Household appliances and office equipment are equipped with a metal shell grounding line, such as its insulation damage shell charged, the current along the installation of the grounding line leaked into the earth to achieve the purpose of security, otherwise it will be a hazard to personal safety.
3, lightning strike grounding.
Lightning strike grounding to prevent in the thunderstorm season, tall buildings, various types of communication systems and antennas erected on the building and some other facilities were struck by lightning, need to install lightning rods, and then lead it to the installation of the lightning strike grounding system with a wire.
4, electromagnetic radiation grounding.
In some important sectors in order to prevent electromagnetic interference, the electronic equipment installed shielding network, the installation of the shielding network should be connected to the corresponding grounding system, and requires grounding resistance ≤ 4 Ω.
