DC current immunity single cores from Long Line Electronic Company Limited are designed for high linearity and accuracy, supporting transformer accuracy classes from 0.5 to 0.1 across a current range of 1.5 - 200A. Their compact design reduces core size by volume and weight, making them ideal for space-constrained applications in electronic energy meters and watt-hour meters.
The single-core construction simplifies assembly while maintaining the high accuracy required for metering transformers. These cores are particularly valued in electronic power systems where DC interference can disrupt measurement precision. Their good temperature stability ensures consistent performance in varying thermal conditions, a critical factor for long-term reliability.
Importers targeting the metering sector will find these cores suitable for systems where DC immunity and compactness are priorities. The cores’ ability to maintain accuracy in high-DC environments makes them a preferred choice for modern electronic meters, where space and performance are equally important.
| Core Type | Single (nanocrystalline or amorphous) |
| Current Range | 1.5 - 200A |
| Accuracy Class | 0.5 - 0.1 |
| Primary Application | DC current immunity transformers in electronic energy meters |
| Secondary Application | Metering transformers in watt-hour meters |

Long Line Electronic Company Limited is based in Daxing District, Beijing, China, and specialises in magnetic components for precision applications. Their single cores are tailored for the metering sector, with a focus on DC current immunity and compact design. The supplier’s location in Beijing provides access to key industrial hubs, facilitating efficient production and distribution.
The company’s harbor-tier trust level reflects a baseline of reliability, though buyers should note the lack of recorded response metrics. This highlights the importance of direct communication to confirm technical specifications, lead times, and customisation options. Their product descriptions emphasize performance attributes like linearity and accuracy, which are critical for buyers in the power metering industry.

Before placing an order, confirm the supplier’s ability to meet your exact accuracy class and current range requirements. Request detailed specifications for linearity and temperature stability, as these directly impact metering performance. Third-party test reports can provide additional assurance of compliance with industry standards.
Clarify logistics details, including lead times for customised cores and standard Incoterms like FOB Beijing. Packaging should be verified to prevent damage during transit, and payment terms typically include a deposit with the balance due prior to shipment. Discuss options for sea or air freight based on urgency.
Upon receipt, inspect the cores for dimensional accuracy and coating integrity, as these affect assembly and insulation. Perform functional tests to validate DC immunity and accuracy under your operating conditions. Request a certificate of conformity to ensure the cores meet the necessary standards for your regional power infrastructure.
