Composite Silicone Cable With Silver STP High Frequency Wire UTP Wires And Single Low Capacity Wires
As an ISO 13485 certified medical cabling innovator, Conectmed manufactures high-performance composite silicone cable solutions on master spools. Specifically engineered for complex diagnostic layouts and surgical robotics, our custom multi-core wire (Model: CMS418) integrates silver-plated STP (Shielded Twisted Pair) high-frequency lines, standard UTP data channels, and ultra-low capacitance single strands under a single jacket. This hybrid structural layout ensures simultaneous power delivery and zero-attenuation data telemetry while maintaining elite flexibility.
This Composite Silicone Cable With Silver 3*30AWG STP High Frequency Wire 2*30AWG UTP ,1P*26AWG and 1P*24AWG UTP Wires And 4 *28AWG Single Low Capacity Wires .It is used in comprehensive medical devices,Especially for Radiofrequency ablation
Both the conductor and shield in this cable adopt extreme flexible silver plated copper alloy 0.05mm,0.06mm or 0.08mm Diameter.
Rfa medical(RFA treatment,Radiofrequency ablation,Nano Knife) is more and more used in Noninvasive operation and save more lives ,decrease patients’ pain.
Radiofrequency ablation has obvious advanges:
- Short ablation time: only 90 ultrashort pulses of 100 milliseconds are needed for a solid tumor of 3 cm;
- The treatment effect is thorough: the boundary of the nanoknife ablation area is clear, and at the same time, important tissue structures are protected, and the treatment effectiveness is greatly improved.
- The effect process can be monitored in real time: image navigation and monitoring can be performed through ultrasound, CT and MR
It usually need to cable to be flexible,high frequency with very small attenuation and low EMI and Capacity influence,so as to realize an accurate RFA treatment. Considering these requirements for the cable,even in the same cable,we choose different specification conductor even the difference is very small (PS,this caused a cost increase very much).
Silver plated to assure the superconducting,Alloy to assure the durability of the cable,Shielded twisted pair(with AL foil double shielded)to assure a low attenuation ,high grade FEP and fine process to assure a low capacity in a limited diameter.
This type of cable is also ideal for APC treatment (need extra insufflation needle to assist)
The transmission of high-frequency electricity is related to multiple factors, such as the high-frequency generator, cable, electrode, etc. If a regular wire is used for APC treatment, it may cause wire heat damage or unstable power transmission, which can affect the treatment effect and safety.
Therefore, APC treatment requires a special high-frequency cable, which should meet the following features:
Low loss: The high-frequency cable needs to reduce signal loss as much as possible to ensure stable power transmission.
Anti-interference: The high-frequency cable needs to have a certain anti-interference ability to prevent external interference with signal transmission.
Good insulation performance: The high-frequency cable needs to have excellent insulation performance to ensure safe and reliable power transmission.
High temperature resistance: The high-frequency cable needs to withstand high-temperature environments to prevent cable melting or burning due to overheating.
Therefore, APC treatment requires the use of a special high-frequency cable and cannot be treated with a regular wire. When choosing a high-frequency cable, it is necessary to pay attention to its applicable frequency range, voltage level, insulation material, and other characteristics.
Technical FAQ & Validation Timeline for Silicone Composite Cables
Q1: Can Model CMS418 withstand repeated hospital autoclave steam sterilization cycles?
A: Yes. The outer jacket is compounded from cross-linked high-tier medical silicone rubber, which preserves its mechanical tensile strength and flexibility during extensive steam autoclave processes. The internal PTFE/FEP core insulations prevent inner conductor shorting under high thermal loads.
Q2: How does the high-frequency Silver STP section prevent signal cross-talk?
A: The silver-plated twisted pairs are wrapped in a 100% coverage aluminum-Mylar foil shield combined with a high-density braided tinned copper matrix. This dual-layer isolation ensures that high-bandwidth data lines are fully insulated from electromagnetic fields generated by adjacent power or single low-capacity signal wires.
Q3: What is the typical factory validation and delivery timeline for this custom spec?
* Day 1–2: Engineering alignment on multi-core matrix, shield density, and cross-talk validation.
* Day 3–4: Initial per-meter direct factory wholesale quote dispatch based on target annual volumes.
* Day 7–10: High-frequency attenuation and capacitance matrix testing for physical prototype samples.
