PROTECT / CPS / 02
Cable Protection Systems
Crush- and abrasion-resistant, chemically inert ePTFE/PTFE jacket systems package copper and fiber while allowing internal cables to move through complex routes, vibration and harsh fluids.

01 / CONFIGURATION DIRECTIONS
Select a configuration from the application boundaries
These configurations establish a practical discussion starting point. The final product requires a controlled specification based on interface, length, installation and validation conditions.
Fiber bundle protection
Allows fiber movement inside the cover to reduce installation damage.
Backshell-integrated system
Compatible with M85049/88 or similar banding-platform backshells.
Match a solution direction to the link target
Solution codes support early technical discussions by aligning protocol, construction, link boundaries and application in one view.

The table covers protection-system material and temperature values; electrical or optical values for the enclosed copper or fiber must be specified separately.
Technical referenceValues are confirmed against category, gauge, length and termination
03 / TYPICAL CONSTRUCTION
From functional core to terminated interface
Protected cable
Original diameter, temperature, motion and sensitive surfaces are confirmed.
Isolation buffer
Reduces imprint, friction and thermal effects from protection materials.
Main protection
Extruded jacket, ePTFE, fiber or metal braid provides the defense.
Closure and branch
Sleeving, wrapping, tying or custom branching supports installation and service.
End restraint
Rings, backshells or strain relief control fray and edge wear.

Typical applications
- Avionics high-speed harnesses
- Defense-vehicle interconnects
- Complex pass-through and tight bends
- Vibration, oil and chemical exposure
Interfaces & delivery
- Secondary cable or harness covering
- M85049/88-style backshell direction
- Custom diameter, branch and end treatment
ENGINEERING NOTE
Secondary protection changes harness diameter, mass, flexibility and cooling and must be assessed with the original cable and routing envelope.
