Silicone Cables

With increasingly stringent fire safety regulations worldwide, the industry faces new challenges in meeting these life-saving standards. One material that is gaining importance is silicone.

In the cable industry, special silicone sheaths with specific fillers are used to create a ceramic protective layer around conductors in the event of a fire. This ceramic layer guards against short circuits and prevents the exposure of bare wires for hours after the incident. These cables find applications not only in building construction but also in the rapidly growing field of electromobility.

Rubicon can provide a complete turnkey production line and process technology for manufacturing these specialized cables.

Silicone cables have become indispensable in today’s world of electronics and electrical engineering. Their remarkable properties, including high flexibility, excellent temperature resistance, and chemical resistance, make them a popular choice across a wide range of applications.

These cables are crafted from high-quality silicone rubber, which imparts the following exceptional characteristics:

• High Flexibility: Silicone cables exhibit extreme flexibility, allowing them to bend without breaking or sustaining damage. This property makes them ideal for applications requiring movement or flexibility, such as in moving machines or robots.
   
• Temperature Resistance: Silicone cables can withstand extreme temperatures, both high and low. They remain flexible and functional within a range from -50°C to over 200°C, depending on the quality of the silicone.
   
• Chemical Resistance: Silicone cables are resistant to many chemicals, oils, and solvents. This quality makes them well-suited for use in industrial environments where they may come into contact with various substances.
   
• Weather Resistance: These cables are UV-resistant and can be safely used outdoors without being damaged by sunlight or weathering.

In summary, silicone cables offer a reliable and versatile solution for various critical applications.

Silicone cables find extensive use across various industries due to their versatile properties. Let’s explore some of the key application areas:

• Medical: Silicone cables are commonly employed in medical devices and instruments. Their ability to be sterilized and meet stringent healthcare industry requirements makes them ideal for critical applications.
   
• Automotive: Within the automotive industry, silicone cables play a crucial role. They are utilized in engines, sensors, and other components where they must withstand both heat and vibration.
   
• Aerospace: Silicone cables also find application in aerospace engineering. Their durability allows them to withstand the extreme conditions of space travel and aircraft operation.
   
• Power Generation and Distribution: Silicone cables are essential in power stations, solar plants, and wind farms. They ensure safe and efficient transportation of electrical energy.

To manufacture silicone cables on a large scale, specialized extrusion lines are necessary to achieve precise and efficient production processes.

The production of silicone cables on a large scale necessitates cutting-edge extrusion lines. These lines comprise a series of machines and equipment that facilitate the silicone extrusion process. Let’s delve into the key components of an extrusion line:

Extruder:
The extruder serves as the central component of the line. It conveys unvulcanized silicone rubber via a screw conveyor to the extruder head within the cooled extruder barrel. There, it is shaped into the desired cable form using a die (forming die).

Shock tunnel:
This tunnel is specifically optimized for pre-vulcanizing the outer surface of the cable. It relies on six high-performance infrared (IR) emitters for heating.

Infrared tunnel:
Designed for rapid vulcanization of the cable cross-section, the infrared tunnel employs six high-performance metal tube emitters. Its upward movement facilitates system startup.

Cooling and drying systems:
Following the vulcanization process, the silicone cables undergo cooling and drying to achieve their final properties.

Peripheral equipment for turnkey projects:
Unwinders, rewinders, vertical and horizontal accumulators, and tape take-offs are customized according to customer requirements.

Quality control:
Modern extrusion lines incorporate advanced sensor systems that monitor cable quality and detect defects at an early stage.

Automation technology:
Most extrusion lines are highly automated enhancing efficiency and minimizing human error.
