YJV XLPE Insulated Solid Copper Fixed Power Cable Industrial Workshop Cabinet Feeder & Municipal Public Facility Bulk Tender Procurement
Product Summary
Product Description
YJV cables are manufactured in strict accordance with the global industrial standards GB/T12706 and IEC 60502. They are widely recognized general-purpose copper core power cables for fixed installation, featuring a compact solid high-purity copper conductor, cross-linked polyethylene insulation, and an extruded PVC outer sheath. Unlike armored YJV22, aluminum core YJLV, and alloy series cables, YJV cables eliminate the additional metal armor structure, achieving a compact size, excellent wiring performance, and economical overall cost. These cables are specifically designed for indoor concealed conduit, cable tray installation, shaft installation, and indoor cabinet interconnection applications, rather than direct burial, avoiding external compression deformation. This cable has become the preferred standard for architectural design institutes, real estate development EPC contractors, factory electrification retrofit companies, and international electrical importers. Our production facilities can provide customized low-smoke halogen-free (LSZH) modifications, different flame retardant ratings, and non-standard core count customization services based on customers' electrical construction drawings. All finished products undergo multi-stage factory laboratory verification to meet international bidding qualification requirements and cross-border customs clearance procedures.

Three Real-World Global Engineering Cooperation Cases
Case 1: Southeast Asia Large Shopping Mall Integrated Electrical EPC Annual Order
A Malaysian commercial real estate EPC company procured a total of 512 kilometers of standard and flame-retardant mixed-specification YJV cables for a large downtown shopping mall project in 2025. After one year of operation in a tropical high-temperature and high-humidity indoor environment, no abnormal heating or insulation aging failure was found; the client signed a multi-year framework supply contract covering five subsequent commercial real estate development projects.
Case 2: Eastern European Automotive Parts Factory Power Grid Upgrade Project
A Hungarian automotive parts manufacturer selected customized Class B flame-retardant YJV series cables for the entire workshop power grid upgrade to meet local industrial fire safety acceptance standards. The initial batch of purchases reached 368 kilometers, and additional replenishment orders were placed for the second phase of the new workshop expansion project.
Case 3: Government Procurement for New Urban Campus Project in the Middle East
A municipal education investment group in the UAE won a bid for a cluster of public schools, ordering 426 kilometers of standard YJV copper cable for pre-installed power wiring in dormitories and teaching buildings, suitable for the dry, hot desert climate. All products passed the inspection of the local power department and were designated as the standard cable for subsequent municipal education infrastructure upgrades.
4. Factory Quality Control and Customized Service Advantages
4.1 Full-Chain Raw Material Inspection and Production Quality Control System
All copper materials are sourced from reputable large-scale smelters and possess complete third-party testing and certification. Each batch of copper materials undergoes purity and resistivity sampling tests before stranding. XLPE and PVC raw materials use branded petrochemical resins, without any recycled waste plastics. Finished YJV cables undergo pressure resistance, heat aging, and dimensional tolerance sampling inspections before leaving the warehouse; any substandard products are scrapped and prohibited from shipment.
4.2 Engineer-Driven Customized Engineering Solutions
The company's in-house R&D department rigorously adjusts sheath materials, flame retardant ratings, and non-standard cross-sectional parameters according to clients' construction design drawings to develop customized YJV cable products that are low-smoke, halogen-free, fire-resistant, and termite-proof for special public building projects. Multiple packaging options can be configured according to the cutting habits of the construction team, including export-grade wooden drum packaging and small industrial reel packaging, minimizing cable waste and optimizing the overall project procurement cost.

5. Professional Selection Standards and On-site Laying Specifications for Electrical Engineers and Procurement Personnel
5.1 Pre-procurement Specification Selection Guidelines
Cross-section Calculation Rules: Calculate the total design load current and actual wiring length based on the distribution diagram, reserving a 12%~23% cross-section margin to offset temperature rise under seasonal peak overload conditions. When the main wiring length exceeds 220 meters, select a larger cross-section specification.
Environmental Differentiation Level Selection: Low-smoke halogen-free (LSZH) fire-resistant YJV type conduit should be used for construction in high-rise public buildings and enclosed underground spaces; HDPE moisture-proof outer sheath upgraded version YJV type conduit should be used for pre-embedded projects in basements and buildings in humid coastal areas.
Layout Optimization Suggestions: When densely wiring, use integrated multi-core YJV type conduit instead of distributed single-core combinations to reduce conduit occupancy and facilitate subsequent daily maintenance and repair.
