”High voltage cable manufacturing expert creates’ super blood vessel ‘for global energy transmission

 

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

• Longitudinal water blocking: semiconductor water blocking tape+aluminum-plastic composite film
Radial water blocking: filled with superhydrophobic material

4. Customized outer sheath

⊙ Cold type: No cracking at -50 ℃
⊙ Anti corrosion type: salt spray resistance>5000 hours
⊙ Rat and Ant proof Type: Added Capsaicin Ingredient

Excellent performance of cables:
1. Power transmission
State Grid ± 800kV Ultra High Voltage Project (with a single line exceeding 2000km)
Saudi Red Sea Photovoltaic Project (High Temperature Resistant 90 ℃ Cable)
2. New energy supporting facilities
Offshore wind power cable (anti bending fatigue>5000 times)
Charging pile super fast charging cable (liquid cooling technology, supporting 600A) 3. Special environment
Russian Polar Cable (-60 ℃ Low Temperature Flexible)
Southeast Asian anti termite cable (passed IEC 60502 additional test)
