Note: The difference between T1 type and T2 type surge protector
The T1 type surge protector refers to the product with the lightning test waveform of 10/350us, and the T2 type surge protector refers to the product with the lightning test waveform of 8/20us.
The main difference between the two types of surge protectors lies in the different test waveforms. The energy of the 10/350us waveform is stronger than the energy of the 8/20us waveform, so in many cases the T1 surge protector is generally 12.5kA, 15kA, 25kA, etc. , T2 surge protector does have 20kA, 40kA, 60KA, 100kA, etc. Although the value of T2 type surge protector looks larger, their test waveforms are different. In fact, the energy of T1 is stronger.
Therefore, the national standard GB50057-2010 requires the installation of a T1 type surge protector in the main incoming line, which is also the first-level surge protector. When selecting the type, pay attention to the surge protector must have a T1 test Iimp (10/350us) test This parameter is generally Iimp is greater than or equal to 12.5kA, and the protection level Up≤2.5kV is enough.
Technology SPD parameter(Note:According to user requirement ,can be customized Uc=140V,440V,550V,voltage range of range of the SPD):
|Type No.||Rated Voltage(V) Un||Continuous Voltage Uc(V~)||Standard Discharge Current In(KA)||

The main function of the power surge protector is to introduce the lightning wave into the ground quickly enough when the lightning strike arrives, and to reduce the residual voltage on the line after the surge protector to protect the safety of the equipment.
The performance of the power supply lightning arrester determines its function. The flow rate, clamping voltage, and response time are the three main performance indicators of the power surge arrester. To clarify the meaning of these indicators requires some in-depth knowledge. The main working principle of the lightning arrester is to protect electrical equipment from lightning strikes by placing the instant lightning wave clamp at a safe voltage. This involves a problem of the size of the lightning. The international standard test index is generally 10kA, 8/20us (Figure 2) The lightning shock wave.
First of all, you must determine what your power distribution system is like, whether it is TT, TN or IT system. After determining the power distribution system, you can choose the protection mode and wiring method of the lightning arrester to select the appropriate lightning arrester.
For example, TN-C uses 3P lightning protection device, TN-S uses 4P, TT uses 3P+N, etc.
