Import 10kv 24kv 35kv Through Core Current Transformer — Buy in wholesale FOB from Supplier in China

This through-core current transformer, model LDZC-10/24/35kV from Beijing Hyliton Power Technology Co., Ltd, is designed for metering and protection in medium-voltage power distribution systems. It operates at a rated frequency of 50Hz or 60Hz with a rated secondary current of either 5A or 1A, accommodating standard measurement circuits. The unit features a toroidal coil structure and is available in both single-phase and three-phase configurations, with autotransformer coil numbering for specific applications.

The transformer's performance is built around key thermal and insulation parameters. It has a rated short-time thermal current of 40kA for 1 second and a rated continuous thermal current of 120% of its nominal rating (120%In). For dielectric strength, it withstands a continuous power-frequency voltage of 3kV for 1 minute. A critical safety feature is its instrument security factor (FS) of 10 or less, which limits secondary output under fault conditions to protect connected meters and relays. The core material is typically grain-oriented silicon steel, standard for such CTs to ensure low loss and accurate ratio performance.

These transformers are commonly specified by electrical contractors, switchgear manufacturers, and utilities for integration into medium-voltage panels and ring main units. The 10kV, 24kV, and 35kV voltage ratings cover a broad segment of industrial and grid distribution networks. Buyers should note that while the listing provides core technical data, specific details like exact physical dimensions, weight, and primary conductor bore size are not stated and must be confirmed directly with the supplier before finalizing an order.

Beijing Hyliton Power Technology Co., Ltd is a manufacturer based in the Haidian District of Beijing, China. Its registered address is on the 6th Floor, Tower B, No.7 of Fenghui Middle Road, placing it within a major technology and industrial hub. The supplier is listed with a 'harbor' trust tier on the platform, which is an initial verification signal. However, the current response rate is 0.00%, indicating no recorded buyer inquiries have been answered through the platform's system.

The company's product listing focuses specifically on medium-voltage current transformers for the Chinese and export markets. The description provides detailed electrical parameters for its LDZC series, suggesting a focus on technical components for the power distribution sector. The listing does not provide information about the company's founding year, number of employees, production capacity, or specific export history. Buyers are advised to request detailed company documentation and product certifications directly to assess manufacturing scale and quality management systems.
