The supplier reports four production lines, 6–10 R&D engineers, 6–10 quality-control staff, ISO 9001 certification, self-operated import/export rights, broad global export markets, and off-peak lead time within 15 working days. Its stated facilities cover R&D, production, sales, marketing, and customer support, and it offers customized solutions. However, most service-capability, innovation-detail, traceability, overseas-support, customer-case, and sustainability fields are explicitly unknown. Audit information identifies TÜV Rheinland, but the audit type and evaluation result are coded values without interpretable conclusions from the provided context.

Supplier typeThe supplier is identified as a limited company in China and is variously classified as a trading company, manufacturer/factory, group corporation, and other entity. Its stated factory location, four production lines, and manufacturing industry classification support manufacturer involvement, although the records also describe the company nature as a trading company.

CertificationsThe supplier reports ISO 9001 management-system certification, and states that some products have been approved by CE and IEC certificates. TÜV Rheinland is listed as the audit organization, but the coded audit type and result cannot be interpreted as a positive or negative audit conclusion.

R&D capabilityThe supplier reports 6–10 years of total R&D-engineer experience and says it has dedicated R&D facilities focused on product design and customized solutions. Specific evidence for new-product launches, SDK availability, private mold design, 3D design, or other measured innovation outputs is unknown.

Production capacityThe supplier reports four production lines and stated output for relays, current transformers, shunts, and current sensors, with off-peak lead time within 15 working days. It also reports broad export-market coverage and self-operated import/export rights, indicating established production and export operations.

Customization capabilityThe supplier explicitly states that it specializes in designing, manufacturing, and delivering customized solutions and has its own R&D, production, and customer-support facilities. Nevertheless, the specific availability of private molds, 3D software design, and other customization services is unknown.

Product Q&A

Q:What is the difference between a moulded case current transformer and a split core current transformer?

A moulded case current transformer is a solid ring of steel in a plastic or resin case and can only be used when you fit the cable through the hole in the middle of the plastic/resin case. A split core current transformer is manufactured with the steel core in two pieces. This enables the core to be separated, allowing you to fit the cores around the cable without disconnecting the cables. The disadvantage with split core current transformers is that they can be larger than standard moulded case

Q:Which way round do the Current Transformers go?

The current transformers must be fitted and connected in the correct way or the meter will not be accurate. The current transformers are marked on two sides: 'P1' and 'P2.' 'P1' must face the mains side and 'P2' must face the load side. 'S1' must be connected to the main side of the meter and 'S2' to the load side. Refer to appropriate wiring diagram of the meter for correct connections.

Q:Can the current transformers be a higher or lower ratio then my maximum load?

The current transformers should ideally be about 80% of the normal running load, thus allowing a 20% allowance of increasing the load in the future.

Q:What is the warranty period?

We provide a 1-year warranty. If the product is defective, please notify us within 3 days of delivery.

Q:What are the payment terms?

We accept Western Union and T/T. A 30% deposit is required, with the remaining 70% due before shipping. We only deliver goods after receiving full payment.
