Alvern Cables Resin Joint Kit

• Provides a professional-grade, all-in-one solution for securely joining and insulating low voltage electrical cables up to 1000V.
• Engineered to create a permanent, waterproof, and mechanically robust encapsulation, making it the industry standard for direct burial, submersed, and outdoor applications.
• Features a high-performance, cold-vulcanizing polyurethane resin system that ensures a reliable, long-lasting joint without the need for heat or specialized equipment.
• Designed for maximum convenience and reliability, the complete kit includes everything required to repair a damaged cable or splice a new cable length.
• Offers a comprehensive range of sizes to accommodate both armoured and unarmoured cables from 1.5mm² up to 300mm², ensuring the perfect fit for any job.

Features

• High-Performance Polyurethane Resin: A two-part, electrical-grade, 100% solids resin that is hydrolytically stable, providing exceptional long-term resistance to water, soil chemicals, and UV exposure.
• All-in-One Twin-Pack Resin Pouch: The resin components are supplied in a pre-weighed, two-part pouch with a separation seal. This eliminates the need for measuring or weighing on-site, guaranteeing a perfect mix ratio every time through a simple hand-mixing technique.
• High-Impact Transparent Mould Shell: The durable, tapered outer mould is transparent, allowing for complete visual inspection during the resin pour to ensure conductors are fully covered and no air voids are present.
• Complete Kit Contents: Each kit is supplied with the twin-pack resin pouch, the transparent mould shell, and EPR tape strips for primary conductor insulation.
• Cold-Cure Application: The resin is a cold-vulcanizing system that processes at room temperature, generating its own heat to cure quickly and efficiently on-site.
• Universal Cable Compatibility: The range is designed to be used with a wide variety of low voltage cables, including PVC, XLPE, and EPR, in both armoured and unarmoured configurations.
• Exceptional Mechanical Strength: Once cured, the resin forms a hard (65 Shore D), tough elastomer that provides outstanding protection against impact, abrasion, and ground pressure.

Benefits

• Simplified, Error-Free Installation: The pre-packaged resin pouch removes all guesswork, ensuring a perfect chemical ratio for every joint. The hand-mixing process is simple, clean, and requires no special tools, saving time and preventing costly errors.
• Permanent and Absolute Sealing: The cured polyurethane resin creates a 100% waterproof and moisture-proof barrier, permanently protecting the cable joint from corrosion and electrical failure, even when fully submersed.
• Guaranteed Installation Integrity: The clear mould shell allows the installer to visually confirm that the resin has completely filled the joint, encapsulating all conductors and ensuring a void-free, professional result.
• Fast On-Site Application: With no external heat or power required for curing, joints can be completed quickly in any environment. The fast-acting formula ensures minimal downtime for the electrical circuit.
• Superior Electrical Insulation: The resin possesses a high dielectric strength (>15 kV/mm), providing excellent electrical insulation and preventing short circuits or faults at the joint for the lifetime of the cable.
• The Right Kit for Every Job: With a comprehensive selection of sizes, you can select the exact kit needed based on your cable's cross-sectional area and overall diameter, ensuring a perfect fit and seal.

Ideal Use

The Metaplast Resin Joint Kit is the definitive solution for joining, repairing, and protecting low voltage cables in harsh environments.

• Underground Cable Repairs: For repairing cables accidentally damaged during excavation or trenching.
• Direct Burial Installations: For joining lengths of cable for new underground power reticulation.
• Outdoor & Garden Lighting: Perfect for creating waterproof joints for landscape lighting, security lights, and decorative features.
• Submersible Pump Connections: Ideal for creating a fully submersible and durable joint for borehole, pool, and pond pumps.
• Industrial & Agricultural: Provides robust protection for cable joints in demanding industrial plants, farms, and irrigation systems.
• Power Supply for Outbuildings: Used to extend power to gate motors, sheds, workshops, and outdoor entertainment areas.

Tips

• Cable Preparation is Key: Ensure cable ends are clean, dry, and free from oil or grease before starting. The quality of the joint depends heavily on proper preparation.
• Thorough Mixing: Once the pouch seal is broken, knead the resin pack thoroughly for the recommended time. Incomplete mixing will result in a soft, sticky joint that will not cure properly.
• Pouring Technique: Cut a corner of the pouch and pour the mixed resin into the mould slowly and steadily from one end. This allows air to escape from the other end and prevents air bubbles from being trapped in the joint.
• Curing Time: Curing time is dependent on the ambient temperature. The chemical reaction is exothermic (creates its own heat), but it will cure faster in warmer conditions and slower in colder conditions.
• Safety First: Always wear the appropriate Personal Protective Equipment (PPE), including safety glasses and chemical-resistant gloves, when handling and mixing the resin.
• Check the Cable Diameter: The most critical step in selecting a kit is to measure the overall diameter (OD) of your cable. Ensure the measured OD is less than the "Max Cable OD" listed for the chosen kit to guarantee a proper seal.
