Source Factory Strength | BXST: 20+ Years of Expertise, Controllable Quality, Maximized Cost-Effectiveness
BXST, as an established factory with over 20 years of experience specializing in the R&D, production, and sales of voltage protectors and surge protective devices, our core advantage has never been about "how many products we produce," but rather "how many customers use our products with peace of mind"—since our inception, our customer complaint rate has consistently remained below 0.5%. As a source factory operating on an independent station, we have engraved "controllable quality, transparent price and thoughtful service" into our development genes, eliminating all intermediate agents and distributors, directly passing on the intermediate profits to customers, allowing every customer to obtain high-quality voltage protectors tested by the market for 20+ years at a reasonable price.

1. Hardcore Production Capability, Fortifying the Foundation of Quality
2. Strict Full-Process Quality Inspection, Zero Hidden Dangers in Delivery
The safety baseline of voltage protectors is determined from the moment components enter the factory. We have made Incoming Quality Control (IQC) and full Bill of Materials (BOM) verification mandatory thresholds for material entry: every batch of varistors and terminal blocks undergoes performance testing; before components are collected by the production workshop, they must be verified item-by-item against the BOM. In the production process, we set up dual checkpoints of self-inspection + IPQC in-process inspection. After completing assembly, workers first conduct a power-on continuity test; IPQC inspectors then spot-check solder joints and wiring firmness. In the finished product stage, our final inspection focuses on core performance indicators—whether the residual voltage value meets standards and whether voltage protection is accurate; every batch of products is re-verified against customer requirements before shipment.

3. Outstanding Customization Capability, Adapting to Diverse Needs
4. Thoughtful After-Sales Service, No Worries About Purchase and Use
We have established a complete and mature after-sales system. Relying on years of industry experience, we have a professional after-sales team to achieve 24/7 full-time response, solving various problems such as installation, use and maintenance for customers one-on-one. Combined with the customer complaint rate of less than 0.5%, we completely eliminate customers' worries about purchase and use.
