PEEK Braided Sleeving for Extreme UHV & HV Wire Protection

Aug 08 , 2025
When it comes to ultra-high vacuum (UHV) and high voltage (HV) environments, wires operate in what can only be described as "hell mode": extreme heat, low pressure, and even radiation exposure.

In these conditions,standard cable sleeving simply doesn't last — it can outgas, degrade, lose insulation performance, and jeopardize the integrity of precision equipment.


PEEK Braided Cable Sleeve


The Challenge: Survival in Extreme Conditions

In UHV and HV systems — whether in advanced research facilities, high-energy physics experiments, or vacuum electronics — wires face:
  • High Temperatures from bake-outs or continuous operation
  • Low Outgassing Requirements to maintain clean, stable vacuums
  • Radiation Exposure that can embrittle conventional insulation
  • Electrical Stress that can cause insulation breakdown over time
Even a small performance drop can mean costly downtime, unreliable measurements, or irreversible equipment damage.


The Solution: PEEK Braided Sleeving

Enter PEEK (Polyether Ether Ketone) braided sleeving — the “armor plating” for cables in UHV/HV environments.

PEEK is renowned for its thermal stability, low outgassing, and radiation resistance, making it ideal for extreme engineering applications.


Key Advantages of PEEK Braided Sleeving:
  • Withstands Extreme Heat – Maintains insulation integrity during bake-outs or high-load operation.
  • Ultra-Low Outgassing – Helps preserve vacuum quality in sensitive chambers.
  • Radiation Resistant – Avoids brittleness or cracking even under prolonged exposure.
  • Mechanical Strength – Protects against abrasion and mechanical stress.

The Payoff: Reliability You Can Count On
Switching to PEEK braided sleeving delivers tangible benefits:
  • Extended Wire Lifespan – Fewer replacements, lower maintenance costs.
  • Stable Signal Transmission – Reduced risk of interference or electrical breakdown.
  • Higher System Reliability – Critical for continuous operation in high-value environments.

For scientists, engineers, and equipment manufacturers, this level of stability is not just a “plus” — it's a competitive edge.
