Composite Insulator
Dalian Tucheng International (TCI Group) supplies composite insulators that are manufactured from silicone rubber and conform to ISO 9001:2008 quality management and ISO 14001:2004 environmental standards. The company states that its units passed the tracking and erosion test at CESI Mannheim, Germany in 2010, indicating a proven resistance to surface discharge under polluted conditions. These features make the insulators suitable for high‑voltage transmission lines, substations and railway electrification projects.
Silicone‑rubber composites typically exhibit a dielectric strength of about 30 kV/mm and are engineered for operating voltages ranging from 35 to 330 kV. Standard product dimensions include lengths of 0.8‑1.5 metres and weights between 5 and 20 kilograms, while creepage distances are commonly set at 150‑300 mm to meet IEC pollution resistance requirements. Mechanical strength is usually expressed as a tensile strength near 30 MPa, providing adequate load‑bearing capacity during installation.
The primary market for these insulators includes national grid operators, railway electrification contractors and international power equipment distributors. TCI Group reports usage in more than 100 countries and highlights collaborations with companies such as ALSTOM, ABB and Siemens. Trade details such as minimum order quantities, lead times and Incoterms are not listed, so prospective importers should contact the supplier to negotiate terms, packaging specifications and required certifications.

Sourcing Composite Insulator from Dalian Tucheng International(TCI Group). - China Import Guide
Importers should first verify that TCI Group can provide up‑to‑date ISO 9001 and ISO 14001 certificates, as well as the CESI tracking and erosion test report referenced in the product description. Request a material test certificate that includes dielectric strength and moisture resistance data to confirm that the insulator meets your project specifications.
Clarify logistics early by asking which Chinese ports (such as Dalian or Tianjin) are used for shipment, the expected production lead time, and the preferred Incoterms (FOB, CIF, etc.). Because the supplier’s response activity is currently low, obtain written confirmation of these details and any freight forwarder recommendations before finalising the order.
Arrange for a third‑party inspection either at the factory or upon arrival at the destination port. Request documentation that includes a conformity declaration, IEC or CE marking where applicable, and a detailed packing list. These steps help ensure that the received insulators satisfy performance criteria and regulatory requirements.
