Surge Protection Device

15 years of lightning protection experience and advanced technology have made us a leader in the industry. As a professional and modern international high-tech surge arrester company engaged in OEM & ODM of surge protection product, we have more than 1,000 models to meet the lightning protection needs of various industries. They are widely used for the lightning protection of the whole building—grounded led lights, transmission line, fire alarm, power meter, internet server, receptacle, workbench, interval, modem, panel...

Based on this, we provide different types of surge protection devices (SPD) for customers to select and buy. In terms of size and shape, our reliable surge suppressors range from mini split to small, big, large, narrow, long, compact, etc. Concerning the current and voltage, our surge arrester device, with low price but good quality, cover high amp, high current, high capacity, transient voltage, low clamping voltage, etc. As for the specific voltage, we offer 120v, 220v, 240v overvoltage/overload regulators to protect electrical equipment and machines. Industrial surge breaker protectors by us can be made ungrounded/mountable, whether wall mount, panel mount, or outlet mount. Besides basic surge diverters against thunder lightning, industrial high-end modular lightning proof surge protector is also available, digital, magnetic, and remote, resettable and adjustable. It is recommended that domestic fireproof/fire shield and waterproof/water resistant surge guard arresters be equipped to avoid lightning strikes. In addition to the single series like single-pole/socket/circuit/port, multi-series surge breakers are for sale as well, both cost-effective, cheaper than that of our counterparts. Our powerful surge protection devices (PDF) can also be made with fuse, alarm, flat cord, led driver, indicator light... For more specific details, please feel free to contact us.

Types Of Surge Protection Device

SPD for Power Supply

Power surge protector, also known as the lightning protector, is suitable for AC 50/60HZ, rated voltage 220V/380V power supply system, to protect indirect lightning and direct lightning effects or other transient overvoltage surges, suitable for households The requirements for surge protection in residential, tertiary and industrial sectors include phase-to-phase, phase-to-earth, phase-to-neutral, neutral-to-earth, and combinations of protection modes.

SPD for New Energy System

New energy lightning protection devices(SPD) (also known as a surge protector, lightning protector, overvoltage protector, lightning surge arrester) are mainly divided into AC/DC lightning surge protectors for photovoltaic solar lightning protection and wind power plants. The DC voltage range is generally 300~1500VDC, and the AC is 385V, 480V, 690V, 1000VAC, etc.

Signal SPD

The signal line SPD is actually a signal lightning arrester, which is installed in series in the signal transmission line, usually at the front end of the equipment, to protect the subsequent equipment-all kinds of signal lines and equipment, and prevent lightning waves from influencing the signal line and damaging the equipment.

SPD for Telecommunication/ Antenna protector

Antenna feeder lightning arrester is a kind of surge protector, which is mainly used for lightning protection for feeder lines. An antenna-feed lightning arrester is also called an antenna-fed signal lightning arrester, an antenna-fed lightning arrester, an antenna-fed line lightning arrester, and an antenna-fed line lightning arrester. In the actual selection, the product's frequency range, insertion loss, VSWR, maximum discharge current, and other parameters are the primary considerations.

Smart Lightning Protective Device

At present, the products we have developed include smart transmission boxes, smart lightning protection devices, smart counters, smart current monitors, smart resistance monitors, multi-function SPD monitors, etc.

Large Discharge Currrent TVSS Lightning Protection Box

The lightning protection box is a kind of lightning protection equipment, which is mainly installed in the power distribution room, power distribution cabinet, AC power distribution panel, switch box, and other important equipment that are vulnerable to lightning strikes.

Surge Protection Device Working Principle

SPD is designed to limit transient overvoltages of atmospheric origin and divert current waves to earth, so as to limit the amplitude of this overvoltage to a value that is not hazardous for the electrical installation and electric switchgear and control gear.

The three types of SPD:

Type 1 SPD

The Type 1 SPD is recommended in the specific case of service-sector and industrial buildings, protected by a lightning protection system or a meshed cage.

Type 2 SPD

The Type 2 SPD is the main protection system for all low voltage electrical installations. Installed in each electrical switchboard, it prevents the spread of overvoltages in the electrical installations and protects the loads.

Type 3 SPD

These SPDs have a low discharge capacity. They must therefore mandatorily be installed as a supplement to Type 2 SPD and in the vicinity of sensitive loads.
