0.01% Defect Rate
Our manufacturing floor implements rigorous quality control that ensures almost all of our SPD components perform above standards.
Effective MOV Selection
HIITIO carefully selects LKD MOVs with a tight tolerance of ±10% for accurate voltage response, enhancing product reliability and stability.
With high-quality MOVs, our surge protectors are safe for up to 5 years, consistently meeting or exceeding industry benchmarks for durability, safety, and performance.
Quality Control in Injection Molding
As an SPD manufacturer, HIITIO utilizes high-strength flame-retardant materials for plastic housing.
Our precision injection molding machines produce casings that are free of defects and bubbles, ensuring a smooth surface.
This process guarantees both the safety of the SPD under high temperatures and electrical stress, as well as an aesthetically pleasing product appearance.
Reinforced Metal Components
HIITIO engineers meticulously calculate and measure the current-carrying capacity of the metal components in our SPDs.
By using wider and thicker metal parts, we efficiently divert lightning currents. This advanced material choice not only extends the operational lifespan of our surge protection devices but also enhances overall safety standards.
Pluggable Surge Protection Device
A pluggable Surge Protection Device (SPD) consists of a protection module and a base.
Manufacturing a high-quality pluggable SPD involves over 20 meticulously controlled production processes.
HIITIO enforces strict quality control at every step, from component selection to precise assembly and thorough testing, ensuring the safety and reliability of each SPD. In case of failure, a pluggable SPD can be quickly repaired by replacing the module.
Advanced Manufacturing Processes and Tooling
For SPD manufacturers, optimizing processing tools and manufacturing processes is crucial for enhancing product quality and production efficiency.
HIITIO focuses on precise tooling design and advanced techniques, including custom tooling for butt welding of disconnectors, to ensure reliable performance and longevity of SPDs.
Regular maintenance of tools and continuous process improvements are essential for upholding high production standards.
Unique Trigger Release Technology
As an SPD manufacturer, HIITIO’s surge protection devices feature innovative trigger release technology and high-quality solder from reputable brands.
The soldering temperature is precisely matched to the SPD’s type and rating, incorporating an advanced tripping mechanism with opposing chambers that effectively isolate and extinguish arcs.
This unique manufacturing process minimizes the risk of arc re-ignition, significantly extending the SPD’s operational lifespan.
