Understanding Silicone Rubber Cable
1. Introduction to Silicone Rubber Cables
- What is a Silicone Rubber Cable?
- Why Choose Silicone Rubber?
- Silicone rubber cables are resistant to high temperatures (+200℃) and low temperatures (-60℃). It is also incredibly flexible. The only other material that can reach the same temperature is Teflon, but this material cannot be used for larger square cables.
2. Key Characteristics of Silicone Rubber Cables
Electrical Properties
