M13 Heavy-Duty Resin Cast Cable Joint Kit for Four-Core Cables

Product Overview

The JINH M13 Resin Cast Cable Joint Kit is designed for joining and insulating compatible four-core electrical cables in installation, maintenance, and repair applications. It is intended for cable connections that require an enclosed joint structure and a resin-based sealing process.

As part of the JINH M10–M15 resin cast cable joint series, the M13 is designed for a larger cable range than the smaller models. According to the supplied product specifications, it accommodates four-core cables with cross-sectional areas from 4 × 25 mm² to 4 × 50 mm² and cable outer diameters from 21 mm to 43 mm. These ranges help installers identify whether the kit is suitable for a particular cable before starting work.

The M13 combines a protective housing with sealing and insulation accessories. When installed according to the instructions, the resin compound fills the designated space around the cable joint, helping form an enclosed barrier against moisture and external contaminants. The suitability of the finished joint depends on correct cable preparation, proper compound mixing, complete filling, and compliance with the installation requirements.

Main Features

1. Designed for Larger Four-Core Cables

The M13 is intended for compatible four-core cables with conductor cross-sectional areas of 4 × 25–4 × 50 mm². Its specified cable outer diameter range is 21–43 mm.

Before selecting a cable joint kit, users should check both the conductor cross-sectional area and the complete cable's outer diameter. These are different measurements, and both are important when determining compatibility. Cable construction, insulation thickness, and the shape of the cable can also affect the fit.

2. Protective PP Housing

The kit includes a PP shell and a matching cover. These components form the outer enclosure for the prepared cable joint and help keep the resin compound in the designated area during installation and curing.

The housing also provides a defined space for arranging the connection and applying the sealing materials. Installers should check that the housing closes correctly and that the cable enters and exits without placing excessive stress on the joint.

3. Resin-Based Sealing and Insulation

The M13 kit shown in the product images includes A&B two-component compound for the resin-filling process. After the two components are prepared according to the supplied instructions, the compound is used to fill the designated space inside the housing.

Once properly cured, the compound helps encapsulate the cable connection and provides insulation and sealing around the joint. Correct mixing, thorough preparation, and sufficient curing time are essential to achieving the intended result. The compound should be handled in accordance with its product instructions and applicable safety requirements.

4. Supporting Installation Accessories

The pictured kit includes a sponge strip, insulating tape, a PP cover, and packaging for the resin compound. These accessories support the installation process by helping prepare the housing, manage the cable entry areas, and complete the sealing operation.

The exact contents should be checked against the packing list for the supplied batch, particularly when the kit is purchased in bulk or used for a project with specific installation requirements.

Installation Guidance

A proper installation process is important for the performance of a resin cast cable joint. Before beginning, disconnect the relevant electrical supply and verify that the cable is safe to work on. Installation should be carried out by qualified personnel in accordance with applicable electrical regulations.

First, check that the cable type and dimensions fall within the M13 specifications. Prepare the cable ends and complete the electrical connection using an appropriate connector or jointing method. The electrical connection hardware is not identified as part of the pictured kit, so users should confirm which connection components are supplied separately.

Next, position the sponge strip and arrange the cable joint inside the PP housing as indicated in the installation instructions. Prepare and mix the A&B compound according to the manufacturer's instructions. Avoid using an incorrect mixing ratio or allowing the compound to cure before the filling process is complete.

Pour the prepared compound into the designated area, ensuring that the joint is filled as required by the product instructions. Secure the housing and cover, and complete the sealing steps using the supplied accessories. Allow the compound to cure for the specified period before moving, burying, energizing, or otherwise placing the joint into service.

The exact installation sequence may vary according to the cable structure and the instructions supplied with the product. Always follow the product's official installation guidance.

Typical Applications

The M13 can be considered for compatible four-core cable connections in electrical installation, equipment wiring, cable repair, and maintenance projects. Its resin-filled enclosure is intended for applications where the cable joint needs additional insulation and protection from environmental exposure.

The supplied product images also illustrate use in underground or underwater environments. However, suitability for direct burial, permanent immersion, or other demanding conditions must be verified against the actual product's tested protection rating, resin properties, cable configuration, and installation requirements. Do not assume that every installation environment is suitable without confirmation.

Why Choose the JINH M13?

The M13 offers a kit-based approach to cable joint sealing, bringing the housing and supporting accessories together for a more organized installation process. Its defined cable size range makes it easier for buyers and installers to evaluate compatibility during product selection.

For distributors, electrical contractors, and maintenance teams, the M13 may be a useful option when a resin-based cable joint is needed for compatible four-core cables. Buyers should confirm the required quantities, cable dimensions, working environment, and technical standards before ordering.

JINH supplies electrical connection products for different installation requirements. For project orders, customers can provide their cable specifications, application details, and estimated quantities to help determine whether the M13 is the appropriate model.

Ordering and Compatibility

Before purchasing, confirm the conductor cross-sectional area, cable outer diameter, number of cores, and installation environment. If the joint will be used in a buried, wet, or submerged location, request the relevant technical documentation and confirm that the finished installation meets the project's protection requirements.

For bulk orders or customized requirements, contact JINH with the cable dimensions and application details. The sales team can help review product compatibility and provide the available technical information for the M13 Resin Cast Cable Joint Kit.
