Ergom PT-4 Heat Shrinkable Cable Breakout for 4-Core Cables 120-300mm2

The Ergom PT-4 is a high-quality heat shrinkable cable breakout specifically engineered for 4-core cables with cross-sections between 120 and 300 mm2. This component is designed to provide a robust seal at the cable crotch, effectively preventing the ingress of moisture, dust, and other environmental contaminants. By utilizing advanced heat-shrink technology, the breakout conforms tightly to the cable geometry, offering reliable electrical insulation and mechanical reinforcement for critical termination points in industrial and commercial power distribution systems.

Advantages

The primary benefit of the Ergom PT-4 lies in its superior sealing capabilities, which significantly extend the service life of cable installations by protecting sensitive crotch areas from corrosion and environmental degradation. Its durable material composition ensures excellent resistance to chemical agents and mechanical stress, maintaining structural integrity under diverse operating conditions. Furthermore, the installation process is straightforward and efficient, allowing for rapid application that saves time during complex electrical projects while ensuring consistent, professional-grade results.

Suitable for

• Sealing 4-core power cables in industrial electrical networks
• Protecting cable crotches in outdoor and indoor installations
• Enhancing moisture resistance in cable termination assemblies
• Applications requiring reliable insulation for cross-sections of 120-300 mm2

When it may not be suitable

This breakout is specifically designed for 4-core cables and will not provide a proper seal for cables with a different number of cores. It is also not intended for use on cables outside the specified cross-section range of 120 to 300 mm2, as the shrink ratio may be insufficient to ensure a secure and airtight fit.

Key specifications

• Type: 4-core heat shrinkable cable breakout
• Compatible cable cross-section: 120-300 mm2
• Material: Heat-shrinkable polymer
• Function: Environmental sealing and mechanical protection

How to use

To install the Ergom PT-4, first ensure the cable crotch area is clean, dry, and free from debris. Slide the breakout over the cable ends and position it firmly into the crotch. Apply uniform heat using a gas torch or a heat gun, starting from the center and moving outwards towards the fingers and the main body. Continue heating until the material has fully shrunk and the adhesive liner has flowed to create a complete seal. Allow the component to cool completely before applying any mechanical stress to the cable.

What to consider before purchase

• Verify the number of cores in your cable matches the 4-core design
• Ensure the cable cross-section falls within the 120-300 mm2 range
• Confirm that appropriate heating equipment is available for installation
• Check environmental conditions to ensure compatibility with the material properties

Usage recommendations

Always follow standard electrical safety protocols when working with cable terminations. Ensure that the heat source is controlled to prevent overheating or burning the material, which could compromise its insulating properties.
