99.99% Surge Protection

Maximize Protection With Greater Precision and Improved Durability

We use MOVs supplied by LKD and GDTs from Vactech to ensure the stability and lightning protection effectiveness of our surge protectors.

We use metal lead pins with a thickness of 0.8mm and a width of 8mm, capable of handling high electrical potentials without easily breaking.

Our R&D team’s optimized low-temperature trip device and soldering process enhance the arc suppression and fire prevention capabilities of our surge protectors.

We use enhanced flame-retardant plastic casings to ensure the flame resistance of our SPDs. We select high-quality brass, red copper, and phosphor bronze components to ensure corrosion resistance during sea transportation

Only surge protectors that meet our testing standards are approved for shipment. All SPDs are certified by TUV, CB, and CE.

Surge Protective Device SPD module Metal Oxide Varistors MOV and Gas Discharge Tube GDT

The market has many low-quality surge protectors. LSP uses top MOVs and GDTs, ensuring stable performance and protection after 10 strikes at In: 20kA.

Surge Protection Device SPD Metal Oxide Varistors MOV

Conventional varistors' design causes uneven heat distribution, leading to failures. LSP's flat tripping device with customized contacts ensures even heat distribution and durable performance without failures.

Surge Protection Device SPD module Metal Oxide Varistors MOV

Traditional surge protectors have insufficient disconnection distance and filament formation, risking fires. LSP's flat disconnection device forms an independent chamber, isolating and extinguishing arcs, preventing fires, and ensuring complete isolation of electrodes.

Surge Protective Device SPD Changing the Grounding Port Direction Improves Convenience V-shape

We redesigned the base of the surge protector and made an "inverted V-shape" design on the base.
