Product Description
Overhead Insulated Conductor Specification Table
| Parameter | Details |
|---|---|
| Product Name | Overhead Insulated Conductor |
| Model | JKYJ (Cross - linked polyethylene insulated overhead cable), JKLYJ (Aluminum core cross - linked polyethylene insulated overhead cable), etc. |
| Conductor Material |
- Copper (Cu): High conductivity, good mechanical properties.
- Aluminum (Al): Lightweight, cost - effective.
- Aluminum Alloy: Improved strength and conductivity compared to pure aluminum. |
| Conductor Cross - sectional Area (mm²) | 16, 25, 35, 50, 70, 95, 120, 150, 185, 240, 300, 400 (customizable options available) |
| Insulation Material | - Cross - linked Polyethylene (XLPE): High thermal resistance, excellent electrical insulation performance, and good mechanical properties.
- Polyethylene (PE): Cost - effective, suitable for low - voltage applications. |
| Insulation Thickness (mm) | - For 0.6/1kV cables: Varies from 1.0 to 1.4 depending on the conductor size.
- For 6/10kV cables: Ranges from 3.4 to 4.5 based on the cross - sectional area of the conductor. |
| Rated Voltage (kV) | 0.6/1, 6/10, 8.7/15, 12/20, 18/30, 21/35 |
| Test Voltage | - Power - frequency withstand voltage: Conducted for a specified time (e.g., 5 minutes) at a voltage level higher than the rated voltage (e.g., 2.5 times the rated voltage for 10kV cables).
- Impulse withstand voltage: Tested with standard impulse waveforms to ensure insulation integrity under transient over - voltages. |
| Temperature Rating | - Long - term operating temperature: Up to 90°C for XLPE insulation and 70°C for PE insulation.
- Short - circuit temperature: 250°C for XLPE and 160°C for PE (for a short - duration short - circuit event). |
| Mechanical Properties | - Tensile strength: Varies depending on the conductor material. For example, copper conductors have a relatively high tensile strength (e.g., ≥ 205 MPa), while aluminum alloy conductors typically have a tensile strength of ≥ 150 MPa.
- Elongation at break: Copper conductors usually have an elongation at break of ≥ 30%, and aluminum alloy conductors have ≥ 15%. |
| Bending Radius | Generally, the minimum bending radius is 15 times the outer diameter of the cable for installation purposes to prevent damage to the insulation and conductor. |
| Environmental Resistance | - Temperature range: Can operate in a temperature range of - 40°C to + 70°C.
- UV resistance: The insulation materials are formulated to resist degradation from ultraviolet radiation, suitable for long - term outdoor use.
- Moisture resistance: The insulation provides good protection against moisture ingress to maintain electrical performance. |
| Standards Compliance | Complies with international standards such as IEC 60502, as well as national standards like GB/T 12527 in China and ASTM standards in the United States. |
