Are your high-voltage cables facing these challenges？
Partial discharge caused by insulation eccentricity (common cause of failure in 110kV cables)
Conductor oxidation increases resistance (a wind farm loses over 8 million annually due to copper conductor impurities)
Damage to shielding layer causes electric field distortion (TOP1 investigation results of subway power supply accidents).
Insufficient weather resistance of the protective sheath (cracks appear in coastal projects within 3 years)
Our solution:Newheek high-voltage cables achieve a maintenance free lifespan of 25 years through a “four-dimensional protection system”!
Why are our cables more reliable?
1. Ultra pure conductor
✓ Oxygen free copper purity ≥ 99.99% (detected by ICP-MS)
✓ Conductor compression coefficient reaches 0.93 (better than the national standard by 20%)
2. Military grade insulation system
✓ Three layer co extrusion technology (inner and outer shielding+insulation layer one-time molding)
✓ 0.05mm ultra-thin control (industry average 0.1mm)
3. Intelligent water blocking design
✓Vertical water blocking: semiconductor water blocking tape+aluminum-plastic composite film
✓Radial water blocking: filled with superhydrophobic material
4. Customized outer sheath
✓High cold type: No cracking at -50 ℃
✓Anti corrosion type: salt spray resistance>5000 hours
✓Rat and Ant proof Type: Added Capsaicin Ingredient
