Description

Technical Field

It also points out the technical deficiencies: "When the capacitor is large, a longer clamp is required for clamping and fixing. When the clamp is large, the top of the clamp is too high, resulting in unstable fixation when clamping the capacitor, which can easily cause the capacitor to shake, thereby causing the wiring to loosen."
