Cross-linked Polyethylene (XLPE): Revolutionary Development and Market Potential Customer in Cord and Wire Insulation Materials
A cutting-edge material with a three-dimensional network framework, cross-linked polyethylene (XLPE) has actually reshaped international power transmission by pushing the warm resistance limitation of polyethylene from 70 ° C to over 100 ° C. XLPE-insulated wires have changed the technical landscape, with lasting operating temperature levels raising from 70 ° C to 90 ° C and short-circuit allowed temperature levels from 140 ° C to 250 ° C compared to standard PVC cables. This architectural improvement through cross-linking technology improves mechanical residential properties, environmental tension resistance, and chemical deterioration resistance, making XLPE a core material for high-voltage transmission, brand-new energy grid link, and metropolitan below ground grids.
1.Product Revolution: Core Advantages and Performance Innovations of XLPE
XLPE converts straight polyethylene molecular chains into a three-dimensional network by means of physical or chemical techniques, bringing essential efficiency renovations:
- Electrical Efficiency : Maintains outstanding insulation with high insulation resistance and low dielectric loss tangent, secure even at high temperatures.
- Thermal Performance : Withstands decay below 200 ° C, with a 90 ° C long-term functioning temperature and 40-year life span, much going beyond typical PE’s 70 ° C restriction.
- Mechanical Performance : Enhanced hardness, stiffness, and influence resistance, overcoming environmental anxiety splitting.
- Environmental Safety : Burning creates only H TWO O and CO TWO, ideal for below ground stocking dense areas.
| Efficiency Indicators | XLPE | Common PE | PVC |
|---|---|---|---|
| Lasting working temp. | 90 ℃ | 70 ℃ | 70 ℃ |
| Short-circuit temperature. | 250 ℃ | 140 ℃ | 160 ℃ |
| Life span | 40 years | 20– 25 years | 15– twenty years |
| Burning items | H ₂ O, CO TWO | Black smoke, harmful gas | Chlorine, hazardous smoke |
2.Refine Advancement: Competition and Development of 3 Cross-linking Technologies
Three mainstream modern technologies dominate XLPE wire manufacturing:
- Inert Gas Cross-linking (Dry Chemical) : Makes use of peroxide agents, appropriate for 500kV high-voltage cables with excellent electrical residential properties.
- Silane Chemical Cross-linking (Cozy Water) : Hydrolyzes in 85– 95 ℃ water, limited to 10kV medium-low voltage due to moisture absorption.
- Irradiation Cross-linking (Physical) : Makes use of electron accelerators, ideal for ≤ 6kV wires with exceptional warm resistance.
