M14 Large Cable Resin Cast Joint Kit for Four-Core Cable Sealing and Insulation

Product Overview

The JINH M14 resin cast cable joint kit is developed for applications involving compatible four-core cables with relatively large conductor cross-sections. It provides a practical enclosure and resin-filling solution for cable joint insulation, sealing, and moisture protection.

Cable joints are important points in an electrical installation. When cables are connected, the joint area needs appropriate insulation and protection to help maintain the reliability of the complete cable system. The M14 kit combines a protective plastic housing with a two-component resin compound, allowing the joint to be enclosed and filled during installation.

With a specified cable cross-sectional range of 4 × 50 mm² to 4 × 95 mm² and a compatible cable outer diameter range of 28–48 mm, M14 offers an option for projects that require a larger cable joint enclosure than smaller models in the same product series.

The dimensions above describe the stated compatibility range. Suitability for a particular cable depends on its actual outside diameter, cable construction, joint dimensions, and installation conditions. Confirm the cable and jointing requirements before selecting the product.

Protective Housing and Resin-Filling Design

The M14 kit uses a PP protective shell to enclose the cable joint. The shell provides an outer structure for the resin-filling process and helps keep the jointing materials in position during installation.

The PP cover is used to close the housing after the resin has been poured and the assembly has been prepared according to the installation instructions. Together, the shell and cover create an enclosed structure around the joint.

The two-component resin compound is supplied for mixing and pouring during installation. Once prepared and cured according to the manufacturer's instructions, the resin forms a solid filling around the joint area. This filling helps provide electrical insulation and environmental sealing.

The kit also includes a sponge strip and insulating tape. These materials are used as part of the installation process to prepare and wrap the joint area. Their correct placement is important to the overall assembly, so installers should follow the supplied instructions rather than relying on the appearance of the finished product alone.

Main Product Features

1. Designed for Larger Four-Core Cables

M14 is specified for four-core cables with conductor cross-sectional areas from 4 × 50 mm² to 4 × 95 mm². This makes it a suitable option to evaluate for cable connection projects involving larger conductors, provided the cable dimensions fall within the stated compatibility range.

2. Enclosed Cable Joint Structure

The PP shell and cover create an enclosure around the joint. This structure helps contain the resin and provides a defined space for the cable jointing assembly.

3. Resin-Based Insulation and Sealing

The two-component compound is mixed and poured during installation. After curing under the specified conditions, it forms a solid filling that helps insulate and seal the joint area.

4. Installation Materials Supplied Together

The kit includes several materials needed for the joint preparation and resin-filling process, including a sponge strip, insulating tape, and auxiliary packaging materials. Supplying these components together can simplify material preparation before installation.

5. A Practical Option for Cable Jointing Projects

The M14 design combines the housing and resin-filling approach in one kit. It can be considered for electrical installation and maintenance projects where a compatible four-core cable needs an enclosed joint with insulation and sealing protection.

Typical Applications

Depending on the cable type, installation environment, and relevant technical requirements, the M14 resin cast cable joint kit may be evaluated for:

• Electrical cable connection and extension projects

• Cable maintenance and repair work

• Four-core power cable jointing

• Industrial electrical installations

• Outdoor cable installations requiring an appropriately sealed joint

• Projects where moisture protection is required and the complete assembly has been verified for the intended conditions

For underground or underwater use, the complete cable joint assembly must be confirmed as suitable for the actual installation conditions. Do not rely on the product image alone to establish a specific waterproof rating, immersion depth, burial depth, or service life.

Installation Procedure

Correct installation is essential to the performance of a resin cast cable joint. The installer should follow the supplied instructions and applicable electrical safety requirements.

Step 1: Check the cable and kit

Confirm that the cable has four cores, its cross-sectional area is within the M14 range, and its outer diameter is between 28 mm and 48 mm. Inspect the kit and make sure the required components are present.

Step 2: Prepare the cable joint

Isolate the circuit and verify that the cable is de-energized before beginning work. Prepare the cable ends and the connection according to the applicable cable-jointing procedure. Any electrical connectors or conductors used to make the actual connection must be selected separately unless explicitly included in the supplied kit.

Step 3: Position the sponge strip

Wrap and position the sponge strip as directed in the installation instructions. Make sure the joint is properly arranged for placement inside the protective shell.

Step 4: Prepare the resin compound

Mix components A and B according to the instructions provided with the product. Follow the specified mixing procedure and any precautions regarding working time, temperature, protective equipment, and handling.

Step 5: Pour the resin and apply tape

Pour the prepared compound into the housing as instructed. Apply the supplied insulating tape at the specified locations and ensure that the joint assembly is correctly positioned.

Step 6: Close the housing and allow curing

Fit the cover securely and allow the resin to cure under the conditions specified by the manufacturer. Do not energize or place the joint into service until the required curing time and inspection procedures have been completed.

The actual installation method may vary depending on the cable construction and project requirements. The supplied product instructions take precedence over this general overview.
