Voltmen 11KV 3-Core 400 sq mm Straight Through Heat Shrinkable Cable Jointing Kit: Uncompromising Reliability for High-Voltage Networks

In the critical field of medium-voltage power distribution, the integrity of every connection is paramount. A single point of failure can lead to costly downtime, extensive repairs, and significant safety hazards. The Voltmen 11KV 3-Core 400 sq mm Straight Through Heat Shrinkable Cable Jointing Kit is an expertly engineered solution designed to provide a secure, durable, and permanent connection for underground and overhead power cables. Meticulously crafted from superior-quality materials, this kit ensures exceptional performance, long-term reliability, and complete environmental protection for your most demanding electrical infrastructure projects.

This straight-through jointing kit is specifically designed for joining 3-core polymeric insulated (XLPE/EPR) cables with a conductor cross-section of 400 sq mm, rated up to 11KV. It is the ideal choice for utilities, industrial facilities, and large-scale commercial projects where uninterrupted power is not just a requirement, but a necessity.

Superior Engineering for Peak Performance

At the heart of the Voltmen jointing kit lies advanced heat shrinkable technology. Each component is manufactured from cross-linked polymers that are specially formulated to provide outstanding electrical insulation, robust mechanical strength, and impenetrable environmental sealing. When heat is applied, the components shrink snugly over the cable, creating a void-free, homogenous insulation system that restores the cable’s original electrical and mechanical properties.

Key Components and Their Functions:

• Stress Control Tubing: The transition from the cable’s conductive screen to the joint insulation is a point of high electrical stress. Our co-extruded, high-permittivity stress control tubing is applied over the connector and insulation screen cutbacks. It effectively smooths the electrical field, preventing stress concentrations that could lead to partial discharges and eventual insulation breakdown. This is a critical feature for ensuring the long-term life of the joint.
• Triple-Extruded Insulation Tubing: The primary insulation is restored using a heavy-wall, triple-extruded heat shrinkable tube. This innovative component combines three layers in one: an inner stress grading layer, a thick middle insulation layer made of high-quality XLPE material, and an outer conductive layer that reinstates the cable’s insulation screen. This integrated design simplifies installation and eliminates the risk of interfaces between layers, significantly enhancing the joint’s dielectric strength.
• Screening and Earthing System: The kit includes a tinned copper mesh and constant force springs (or solder-block earth braids, depending on the specific model) to provide a continuous and reliable metallic screen across the joint. This ensures electrical safety by providing a fault current path and protecting the joint from external electrical interference.
• Outer Sealing Tube (Jacket): The final layer of protection is provided by a heavy-duty, adhesive-lined outer heat shrinkable tube. This rugged jacket provides exceptional mechanical protection against abrasion, impact, and soil subsidence. The inner adhesive lining melts and flows during the shrinking process, creating a powerful waterproof seal that prevents moisture ingress and protects the joint from chemicals, oils, UV radiation, and other environmental contaminants. This ensures the joint remains fully protected, whether it’s directly buried, installed in ducts, or exposed to the elements.

Unmatched Benefits and Applications

Choosing the Voltmen 11KV jointing kit offers a multitude of advantages over conventional jointing methods, making it the preferred solution for modern power networks.

Core Advantages:

• Exceptional Durability: Built to withstand the harshest conditions, the joint provides decades of maintenance-free service.
• Simplified Installation: The heat shrinkable components reduce the complexity and time required for installation. With clear instructions and color-coded components, the process is streamlined, minimizing the risk of installer error and reducing labor costs.
• Compact and Versatile Design: The finished joint has a slim profile, making it suitable for installation in tight spaces such as narrow trenches or congested cable trays. It is compatible with both compression (crimp) and mechanical shear-bolt connectors.
• Proven Reliability: Each kit undergoes rigorous quality control and is tested to comply with major international standards such as IEC 60502-4, ensuring it meets the highest levels of safety and performance.

Ideal Applications:

• Underground Power Distribution Networks: Perfect for joining cables in urban and rural utility grids.
• Industrial Plants: Reliable for critical power connections in manufacturing facilities, petrochemical plants, and mining operations.
• Renewable Energy Projects: Essential for connecting cables in wind farms and solar power plants where long-term reliability is crucial.
• Infrastructure Projects: Widely used in airports, railways, tunnels, and large commercial buildings.
