WTTZ 4-Core Copper-sheathed Inorganic Insulated Flexible Fireproof Cable

We implement strict quality control throughout the entire production process, including incoming raw material inspection, in-process monitoring, and 100% routine tests on finished cables (conductor resistance, dielectric voltage-withstand, etc.) prior to delivery. Test reports are available for each batch. We provide after-sales support for any quality-related defects arising from proper use.

Standard export packaging: ISPM-15 compliant wooden or steel cable drums for long-length cables, and export cartons for short-length ones. Drums can be palletized for container loading. Cable ends are sealed to prevent moisture ingress. Packing dimensions and gross weight per drum will be provided upon order confirmation.

Yes, we accept customized orders. We can customize conductor cross-sections, insulation/sheath materials, cable construction, voltage ratings, surface printing, and delivery lengths. Please send your technical specification or drawings for an accurate quotation.

Our cables are manufactured in accordance with IEC International Standards as the primary reference, complemented by GB National Standards. We provide comprehensive certifications and documentation including CE Certification, ISO 9001 Quality Management System Certification, and Factory Inspection and Test Reports. For clients with specific regional requirements, we are able to facilitate applications for additional standards certifications upon request.

MOQ varies by cable type. For stock items, shipment can be made within 3-7 working days. For production orders, lead time is typically 15-25 working days, depending on the total ordered length and our production schedule.
