Surge Protector

  SEL series lightning rod is a kind of product, which matches GH model ring type steel lightning rod and ZG model ring type reinforced concrete lightning rod.

  BYW series surge arrestor is applied in satellite TV high frequency, satellite signal receiver, microwave machine station, the feed system of moving communication, which is to avoid the damage to the receiving equipment caused by over voltage of feed inductance.

  BY4 type SPD is series surge protective device (protector in short) is applied in A.C 50/60 Hz, <=380V electric power system such as TT , IT ,TN-S , TN-C and TN-C-S, and used at the equipotential connection of LPZ0A and LPZ31 zone or LPZ0B and LPZ1 zone, which protects the electric network shocked by the thunder or surge over voltage.The protector can be made connecting with remote signaling contact, which is a normal open contact. If one or more of modular of the protector is in malfuction, the contact will be closed, and sending the malfunction signal. The rated value of remote signaling contact is AC36V, 1A.

  BY2 series surge protective device (protector in short) is applied in A.C 50/60 Hz, <=380V in the following electric power system, such as TT, IT, TN-S, TN-C and TN-C-S, applied in the equipotential connection of the joint of LPZ0A and LPZ1 or LPZ0B and LPZ1, which protects the electric net shocked by the thunder or surge over voltage. This protector also can be connected with voltage limitation type SPD to combine “3+1”, used in the TT system. And it’s not applied in the system overdue short circuit current over rated breaking continuous value.

  Voltage limiting type SPD combined with voltage switching type SPD is formed the Group SPD, which is suiting to A.C 50/60 Hz, 380V and under 380V voltage’s electric power system and protects all the distribution systems shocked by the thunder or surge over voltage. Using the combination SPD between phase line and earth line in the distribution system, which not only eliminates the power-frequency continuous current, but also over comes the leakage tripping which results from the bad performance of MOV. So SPD is suitable to all the distribution system, which is with the protection of surplus current. Since the voltage switching SPD is connected between zero line and earth line, at the same time with its much higher maximum continuous operating voltage and enough impulse current capacity, it will have its peculiar superiority when used in TT system.
