外护套

Outer protective sheath for shielded cable harnesses providing environmental and mechanical protection.

技术定义与适配语境
典型 外护套 会按材料、尺寸公差、适配关系和失效风险在 电气设备制造 中评估。

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.

定义
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.
工作原理
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.
材料
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 resistanceand flexibility.
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)
标准
ISO 6722DIN EN 50525
