The cable is delivered using export-standard packing methods to ensure protection during handling and shipment. Depending on order specifications, it can be supplied in coils or wound on durable wooden or plastic reels. Each unit is wrapped with protective film to resist moisture and dust, and outer packaging such as cartons or pallets can be applied for reinforced transport safety. Product details are clearly labeled for easy identification.
Structural Design & Signal Benefits
The cable utilizes 4 pairs of stranded tinned copper conductors, offering improved flexibility and consistent conductivity. The paired configuration helps maintain signal balance and reduces interference between channels. Semi-rigid PVC insulation enhances durability while allowing manageable installation. The braided tinned copper shield effectively suppresses EMI and external noise, ensuring stable data transmission. The PVC outer jacket provides reliable protection against wear, moisture, and mechanical stress.
Installation & Performance Considerations
To achieve optimal performance, the cable should be installed with proper bending radius and without excessive tension. It is advisable to separate the cable from high-voltage lines or strong electromagnetic sources to minimize interference. Grounding the shield correctly can significantly improve noise immunity. This cable is intended primarily for fixed installations and performs best in controlled indoor environments.
FAQ
