Technical Points |
|
Direct burial in soil |
YJV22,YJV32 |
burial depth ≥ 0.7m, top and bottom layers of 100mm fine sand, covered with protective plates; armor layer provides mechanical protection. |
|
Conduit laying |
YJV,VV |
the inner diameter of the protective conduit should be ≥ 1.5 times the outer diameter of the cable, and the conduit opening should be smooth to prevent scratches |
|
Cable trays/trenches |
YJV,YJY |
when multiple wires are arranged in parallel, the fill rate should be ≤40%, and different voltage levels should be separated by layers |
|
Damp/corrosive environments |
YJV23(Polyethylene outer protective layer) |
enhanced moisture resistance and chemical corrosion resistance, suitable for areas along the Hutuo River |
Product Technical Parameters
Current Carrying Capacity Matching:
- Select the cross-section based on the load current. For a 50kW three-phase motor, 35mm² copper core cable is recommended. For loads above 100kW, 70–120mm² or larger specifications are recommended.
- When laying multiple cables in parallel, a derating factor must be considered, typically 0.8–0.9, to prevent overheating.
Voltage Drop Verification:
- Voltage drop must be calculated for long-distance power supply. Lighting circuits should have a voltage drop of ≤5%, and power circuits ≤3%.
- This can be optimized by increasing the cross-section or shortening the power supply radius.
Environmental Adaptability:
- In winter temperatures as low as -10℃, PVC insulated cables should be avoided; XLPE insulated YJV series cables are preferred.
- In high-temperature summer environments, XLPE cables offer superior temperature resistance, ensuring long-term stable operation.
Construction and Maintenance Ease:
- Copper cores offer good flexibility and a small bending radius, facilitating conduit and bend installation.
- Reliable joint connections are less prone to oxidation, reducing the later failure rate.
FAQ
Q: Can I request samples?
A: We can provide you with the samples you need. Please contact our customer service staff, specifying your purchasing requirements and sample description, and providing your shipping address and delivery requirements. We will then compile this information and submit a quotation. After you make payment, we will initiate the logistics process. If a formal cooperation agreement is subsequently reached, the sample cost can be deducted from the final payment.
