(1)All the accessories and raw material suppliers we use are based on quality stability and excellent service.

(2) We have established the industry's highest standard equipment installation process. The wiring uses wire troughs to distinguish between high and low voltage lines to prevent equipment failure caused by voltage conflict. We also use wiring terminals on all the wirings, and each wire is marked with a rubber sleeve. The specific voltage, distinguishes the fire line, the zero line, the ground line, has prevented the potential safety hazard effectively, also facilitated our equipment to be able to solve the problem faster and more safely in the time of the breakdown.
