Product Description

Product Description

Shenghua XLPE Insulated Copper core cable for High-Efficiency Energy Transmission 

The NH-YJV cable is a premium fire-resistant power cable featuring a high-conductivity oxygen-free copper core and cross-linked polyethylene (XLPE) insulation, encapsulated in a durable polyvinyl chloride (PVC) sheath for superior corrosion and moisture resistance . 

Designed to maintain circuit integrity during emergencies, it withstands flames at 750–800°C for 90 minutes (complying with IEC 60331 standards), ensuring uninterrupted power supply to life-saving systems like fire pumps,emergency lighting, and evacuation routes  Rated for 0.6/1kV to 8.7/15kV voltage levels.

 its XLPE insulation delivers exceptional thermal stability (90°C operating temperature), low dielectric loss, and long-term aging resistance, while the robust structure supports installation in tunnels, cable ducts, or loose soil without mechanical stress . Ideal for high-risk environments such as nuclear plants, industrial complexes, and underground transit systems, this cable combines flexibility, flame retardancy (WDZN optional), and compliance with GB12706 standards for global infrastructure safety

Cable Constructions

NH-YJV Cable Structure Description

NH-YJV stands for Normal Heat resistant cable. It is a type of fire-resistant power cable designed to maintain functionality during a fire for a certain period. Here's a breakdown of its structure

Conductor

Fire-Resistant Layer

Typically made of copper, this is the core part of the cable responsible for conducting electricity. It can be a single core or multiple cores depending on the application requirements.

This layer is added around the conductor to protect it from high temperatures and flames. It is usually made of mica tape, which has excellent heat resistance properties .

Cross-Linked Polyethylene (XLPE) Insulation

PVC Sheath :

This layer provides electrical insulation between the conductor and other layers. XLPE is known for its superior thermal stability and dielectric strength compared to PVC (Polyvinyl Chloride) .

The outermost layer, made of PVC, protects the cable from mechanical damage, moisture, and chemicals. It also adds flexibility to the cable .

NH-YJV Power Cable Packing

Our NH-YJV (Fire-Resistant Crosslinked Polyethylene Insulated PVC Sheathed Cable) is securely packaged to ensure optimal protection during international shipping. 

Each cable is precision-wound on robust wooden drums or reusable plastic reels, customized to the cable's length and diameter (e.g., common sizes like 34 or 410 mm²). To prevent damage, drums are tightly bound with steel strapping and fully encased in waterproof polyethylene film, guarding against moisture, dust, and mechanical shocks. 

Clear labeling is affixed to each drum, including essential details like product specifications (e.g., NH-YJV 0.6/1kV), gross/net weights (e.g., 500 kg gross, 450 kg net), and dimensions (e.g., drum diameter 100–120 cm). Crucially, all packaging prominently features the "MADE IN CHINA" label in English, positioned visibly on the drum surface for compliance with global customs regulations and MIC standards. 

This method minimizes handling risks, ensures traceability, and supports efficient logistics for end-users. For full specifications or bulk inquiries, refer to our MIC storefront.
