Outer Protective Sheath Component – Electrical Equipment Manufacturing

Component Specifications

Definition

The outer protective sheath is an external layer in shielded cable harnesses designed to protect internal conductors, insulation, and shielding from environmental factors (moisture, chemicals, UV radiation) and mechanical damage (abrasion, crushing, impact). It serves as the first line of defense, ensuring cable integrity and longevity in industrial applications.

Working Principle

Acts as a barrier against external elements while maintaining flexibility and durability. It prevents ingress of contaminants, reduces electromagnetic interference (EMI) leakage, and provides strain relief at connection points.

Materials

Common materials include PVC (Polyvinyl Chloride), PUR (Polyurethane), TPE (Thermoplastic Elastomer), or LSZH (Low Smoke Zero Halogen) compounds. Material selection depends on application requirements such as temperature resistance (-40°C to 105°C typical), chemical resistance, and flexibility.

Technical Parameters

Flame Rating UL94 V-0 or VW-1
Color Options Black, Orange, Blue, Custom
Diameter Range 3mm to 50mm
Temperature Rating -40°C to 105°C
Abrasion Resistance ≥500 cycles (ASTM D3389)

Standards

ISO 6722, DIN EN 50525
