How Is SOOW Wire Constructed for Durability?
SOOW wire is built with stranded copper conductors, synthetic rubber insulation, and a durable outer jacket made of CPE or rubber. This layered structure is resistant to oil, water, chemicals, UV rays, and abrasion, which enhances its mechanical strength and flexibility. The wire is designed to withstand frequent movement, coiling, and outdoor exposure without compromising electrical integrity.
China manufacturers ensure quality by using bare or tinned copper strands, EPDM or similar rubber for insulation, and a thermoset rubber or CPE jacket for added toughness. B2B buyers should confirm key construction details such as strand class and jacket thickness to meet specific application needs, ensuring durability and performance in their industrial environments.
Typical SOOW Structure Overview
| Layer | Function in Industrial Use |
|---|---|
| Stranded copper | Provides high conductivity and flexibility in machinery |
| Rubber insulation | Offers electrical protection, oil, and heat resistance |
| Fillers/separator | Maintains round cable shape and enhances flexibility |
| Rubber/CPE jacket | Protects against mechanical wear, water, UV, and chemicals |
