General FAQ
Yes, our core products (such as insulators, arresters, and cutouts) strictly adhere to relevant international and regional standards like IEC, IEEE, DIN, BS, AS ,ANSI and Customers' drawings. Our factory is ISO 9001 certified, and specific products have obtained CE, KEMA and other market-specific certifications. We can provide complete technical specifications and certification documents based on your project requirements.
Our porcelain components are made of high-strength electrical porcelain, with bending and compressive strength significantly exceeding standard requirements. For pollution flashover performance, we offer various shed design profiles and different classes of creepage distance to suit light, heavy, and coastal pollution environments, ensuring stable operation under harsh conditions.
Our Zinc Oxide surge arresters feature excellent non-linear volt-ampere characteristics and low residual voltage, enabling them to quickly suppress overvoltages and effectively protect valuable equipment like transformers and switches. Their high flow capacity ensures reliable energy absorption without damage during severe lightning strikes or switching overvoltages. Please refer to the product datasheet for the specific technical parameters of the corresponding model.
Absolutely. Our drop-out fuse cutouts offer full-range breaking capacity, safely and effectively interrupting fault currents from minimum to maximum. Every batch of products undergoes rigorous testing, ensuring their Time-Current Characteristic curves are precise for perfect coordination with upstream protection devices, preventing false or failure operations.
Certainly. We have strong engineering design and manufacturing capabilities and can customize insulators, bushings, fittings, etc., according to your specific drawings or technical requirements (e.g., special dimensions, voltage/current ratings, or mounting methods). Please provide your detailed needs, and our engineering team will develop a solution for you.
We have modern production lines and sufficient raw material inventory, implementing lean production management to ensure on-time order delivery. Simultaneously, we implement a full-process quality control system from raw material intake to finished product dispatch. Each manufacturing step has strict inspection standards, guaranteeing consistent quality in every shipment that matches the provided samples.
We provide comprehensive technical support and installation guidance documents (e.g., installation videos, manuals). For complex projects, we can dispatch engineers for on-site guidance. We have an efficient after-sales service system. Should any issues arise, please contact us within 24 hours. We will respond immediately, conduct problem analysis, and provide solutions, including replacement, on-site technical support, until the issue is resolved.
We offer highly competitive tiered pricing for long-term partners and large-volume purchases. Specific payment terms (e.g., T/T, L/C) can be negotiated flexibly based on our cooperation history and order value, aiming to establish a mutually beneficial long-term partnership. Please feel free to send your specific requirements, and we will prepare a most favorable quotation for you.
