Reasons Why LSP's Surge Protectors Stand Out

Top MOV Materials

We use high-quality LKD MOVs in our surge protection devices. These MOVs offer excellent durability, withstanding a nominal discharge current of 20KA (10 impulses) and a maximum discharge current of 40KA (2 impulses) in 8/20 current impulse.

Innovative Tripping Device

Our independently developed surge protection low-temperature tripping device further enhances arc extinction effectiveness, ensuring the surge protector can safely disconnect from the power grid.

Flame Retardant Ability

Our plastic housing is made of enhanced flame-retardant material (PA6+GF30%), which effectively prevents the spontaneous combustion of SPD.

Thick Metal Parts

We use metal lead pins with a thickness of 0.8mm and a width of 8mm, which is 45% above average and can handle high potentials without breaking easily.

Rigorous Testing

Our spds are rigorously tested, including lightning impulse test, thermal stability test, 48-hour salt spray test, glow wire test and current impulse 8/20 and 10/350 test.
