The choice of product depends on the site’s “power quality assessment report” and load characteristics. We offer a complete product line ranging from capacitors and reactors to SVGs. We can provide a free preliminary power quality diagnosis and recommend the most cost-effective and reliable solution to help you avoid waste caused by “overpricing” or “purchasing the wrong product.”

This is a highly technical and critical issue. Selecting the wrong reactance ratio will not only fail to protect the equipment but may also amplify harmonics and cause electrical fires. We will provide a precise match based on your company’s load type (rather than a simple estimate), along with a selection calculation report, to ensure that the compensation system is safe and free from resonance.
-
SVG not only provide reactive power compensation but also filter out 5th through 13th harmonics and offer phase-by-phase compensation, making them particularly well-suited for addressing three-phase current imbalance issues on-site. Our SVG feature a modular design that supports redundant capacity expansion and boast industry-leading low-loss characteristics, which can significantly reduce your company’s long-term electricity costs.

Capacitor failure is typically caused by two main factors: excessive harmonics and inadequate heat dissipation.
First, we don’ t just sell products — we provide full-life cycle technical support. Before delivery, we assess the on-site harmonic environment to ensure the reactance ratio is correctly matched, thereby eliminating the risk of resonance at the source. Second, our products (such as low-voltage capacitors) feature an over pressure isolation explosion-proof design and strictly adhere to the installation specifications of international brands like Schneider Electric (e.g., ensuring a minimum heat dissipation clearance of 25 mm and a fastening torque greater than 19 N · m) to prevent premature failures caused by improper installation.
-
Our technical team provides 24/7 phone and online support, and most parameter settings or simple malfunctions can be resolved remotely. If the issue cannot be resolved over the phone or online, we promise to arrive on-site within 72 hours (repairs for non-human-caused damage are free of charge during the warranty period). In addition, we provide free annual inspection services during the warranty period to proactively identify potential issues rather than passively waiting for service requests.
-
Of course. We not only sell components but also provide customized assembly services. Whether it’s designing capacitor cabinets based on transformer capacity (we typically recommend configuring compensation capacity at 20%–40%) or customizing wall-mounted or floor-standing SVG modules to fit on-site dimensions, we have extensive experience in non-standard design. We can also directly supply pre-assembled compensation cabinets or filter cabinets, reducing your on-site installation and wiring workload as well as the risk of errors.

Electrical components are long-term investments, so we’re very concerned about how long they’ll last and whether maintenance will be a hassle down the road. Service life and maintenance costs are among our core considerations when designing products. Design Life: Our low-voltage capacitors use high-quality metallized polypropylene film, with a design life of over 100,000 hours (approximately 11 years) under rated operating conditions; Our reactors utilize high-permeability silicon steel laminations and an H-class insulation system, which keeps temperature rise within a reasonable range and significantly delays aging. Routine Maintenance: We advocate for “minimal maintenance and frequent inspections.” We generally recommend conducting infrared temperature measurements every six months, checking the tightness of terminal connections, and visually inspecting the capacitors for any signs of bulging. For SVG, we have built-in intelligent self-diagnostic systems that provide remote early warnings, eliminating the need for frequent manual intervention.
-
Absolutely. Our capacitors and reactors are standalone components with exceptional versatility. As long as the voltage rating and capacity match, our components are compatible with the vast majority of mainstream capacitor controllers on the market. We offer an “ old cabinet retrofit ” service that retains your existing cabinet structure while replacing only the core components (capacitors, reactors, and switching devices), saving you over 50% on retrofit costs.
-
This is precisely where we stand out from ordinary brands. Environmental Adaptability Design: Our capacitors and reactors have all passed rigorous temperature rise tests and can operate stably over the long term at ambient temperatures ranging from -25° C to +55 ° C; SVG modules feature independent air duct cooling, with an IP rating of up to IP54 (dust-proof and splash-proof), and can be equipped with dust filters or water-cooling kits. Special Coatings: All circuit boards are coated with a triple-protection finish (moisture-proof, mildew-proof, and salt-fog-proof), and critical connectors are silver- or tin-plated to effectively resist corrosion. Custom Solutions: For particularly harsh environments, we offer a fully sealed cabinet with a heat exchanger to ensure internal components always operate in a clean, temperature-controlled environment. We have successfully delivered similar projects to numerous steel, cement, and chemical plants, all of which are operating stably.

Absolutely. We fully understand that the costs associated with incorrect equipment selection far exceed the price of the equipment itself, which is why we regard “ pre-sales technical support ” as a core competitive advantage. Simply provide us with the transformer capacity, the types of major loads (such as motors and variable frequency drives), and photos of your existing compensation cabinet or a single-line diagram of the system, and our technical team will issue a “ Preliminary Power Quality Assessment and Equipment Selection Recommendation ” within 48 hours. This document will include: theoretical compensation capacity calculations (taking into account both static and dynamic demands); harmonic spectrum analysis and recommended reactance ratio (7% or 14%); and recommendations for SVG capacity and installation methods (wall-mounted, rack-mounted, or cabinet-mounted). All proposals are accompanied by detailed calculation justifications, and there is no charge for this service. We welcome your inquiries even if you ultimately decide not to proceed with us.
