Description

 


Key Features:

Sealing Mastic Coated:

The RCS-CFT feed-throughs are coated with a high-quality sealing mastic that creates an airtight and waterproof seal. This prevents moisture, dirt, and other contaminants from entering the connection point, ensuring stable electrical performance and long-lasting reliability.

Excellent Electrical Insulation:

These feed-throughs offer superior electrical insulation, crucial for the safe operation of medium voltage cable terminations. This insulation minimizes the risk of electrical faults, including short circuits and leakage.

UV Resistant:

The RCS-CFT feed-throughs are made from UV-resistant materials, protecting them from degradation caused by prolonged exposure to sunlight. This feature makes them ideal for use in outdoor environments where UV exposure is inevitable.

Shrink Ratio 2:1 to 3:1:

With a shrink ratio of 2:3:1, these feed-throughs are highly versatile and can accommodate a wide range of cable sizes. This flexibility simplifies installation and helps with inventory management, as one product can fit multiple cable sizes.

Temperature Resilience:

The feed-throughs are designed to fully recover at a minimum temperature of 130°C, ensuring a secure fit and long-term performance in high-temperature environments. This heat recovery ensures the structural integrity and sealing properties are maintained even under extreme conditions.

Standard Color:

The black color of the feed-throughs is commonly used in electrical installations, ensuring compatibility and uniformity across various components. It is also easier to identify in industrial settings.


Applications:

Sealing and Insulation for Medium Voltage Cable Terminations:

RCS-CFT Heat Shrink Feed-Throughs are specifically designed to provide sealing and insulation for medium voltage cable terminations and connections. These feed-throughs protect cable connections from environmental factors such as moisture, dirt, and mechanical stress, enhancing the safety and performance of electrical systems.

Ideal for Outdoor Environments:

Thanks to their UV resistance, these feed-throughs are perfect for outdoor applications such as substations, power plants, and industrial installations. They ensure long-term protection of cable connections in harsh weather conditions, maintaining system integrity and performance.

Versatile in Harsh Environments:

In addition to being UV resistant, the mastic-coated feed-throughs are resilient against high humidity, salt mist, and extreme temperatures. This makes them suitable for a wide range of applications, from power distribution systems to offshore installations and other demanding environments.
