The kit includes a PP protective shell and cover, sponge sealing strip, insulating tape, and two-component A&B resin.
Its resin-casting design helps provide electrical insulation and moisture-resistant sealing around cable joints.
It is suitable for electrical installation and cable maintenance projects where reliable joint protection is required.
M15 Extra-Large Cable Resin Joint Kit for Large Four-Core Cables
Designed for Large Cable Connections
When working with large power cables, the joint needs appropriate insulation and protection against moisture and environmental exposure. The JINH M15 Extra-Large Cable Resin Joint Kit is designed for compatible four-core cable connections using conductors with cross-sections from 120 mm² to 150 mm².
The kit combines a protective housing with a two-component resin filling system. After the cable joint has been correctly prepared and positioned, the resin is mixed and poured into the housing according to the installation instructions. Once cured under the specified conditions, the resin forms an insulating and sealing layer around the joint.
This design makes the M15 a practical option for electrical contractors, cable installation teams, equipment manufacturers, and distributors looking for a resin-cast cable joint solution for larger cable sizes.
Product Specifications

Before ordering, users should check the cable's actual outer diameter, conductor size, cable construction, and joint dimensions. The conductor cross-section range and the cable outer diameter range are separate selection criteria; both must be compatible with the intended application.
Main Components and Their Functions
1. PP Protective Shell
The PP shell forms the outer housing of the joint kit. It holds the prepared cable joint and the resin during installation and helps maintain the intended shape of the assembly. Its dimensions are designed for the M15's larger cable application.
2. PP Cover
The cover closes the housing after the resin has been poured. It helps retain the assembled structure and protects the resin-filled area. The shell and cover should be correctly positioned and secured according to the supplied instructions.
3. Two-Component A&B Resin
The kit includes A&B resin packaged for mixing before use. The two components must be combined in accordance with the manufacturer's instructions. Correct mixing and pouring are important for achieving the intended insulation and sealing performance.
Users should observe the specified mixing ratio, working time, curing conditions, and handling precautions. These details should be taken from the product instructions or technical documentation rather than estimated on site.
4. Sponge Strip
The sponge strip is used around the prepared joint area as directed by the installation guide. Correct placement helps prepare the assembly for the resin-filling process and supports the intended sealing arrangement.
5. Insulating Tape and Installation Accessories
Insulating tape and the other supplied accessories support the installation process. The exact preparation and wrapping method should follow the instructions for the M15 kit and the requirements of the cable joint being made.
Key Product Features
Suitable for larger four-core cables
The M15 is designed for compatible four-core cables with conductor cross-sections from 120 mm² to 150 mm². Its stated cable outer diameter range is 36–70 mm, making it important to verify both dimensions before selection.
Resin-cast insulation and sealing
The resin-filling structure is intended to provide insulation and sealing around a properly prepared cable joint. The final performance depends on correct cable preparation, suitable materials, complete mixing, proper filling, and adequate curing.
Protective housing design
The PP shell and cover provide a defined space for the joint and resin. This design helps keep the assembly in position during the installation process and forms the external structure of the finished joint.
Installation accessories included
The kit brings together the main housing, resin, sponge strip, insulating tape, and related accessories shown in the product images. Having the main installation materials in one kit can simplify product selection and preparation for cable-joint work. Please confirm the supplied packing list when placing an order.
Multiple models for different cable sizes
M15 belongs to the JINH M10–M15 resin cast cable joint kit series. The series covers different cable size ranges, allowing users to select a model according to the cable specifications rather than choosing one kit for every application.
Typical Applications
The M15 can be considered for compatible large four-core cable joints in electrical installation, power distribution, industrial equipment, and cable maintenance projects. It may also be considered for installations where the cable joint requires additional protection against moisture, provided that the product's verified performance meets the requirements of the site.
The product's suitability for direct burial, permanent underwater use, or other demanding environments must be confirmed against the manufacturer's technical documentation and applicable installation requirements. Do not assume a specific IP rating, voltage class, or environmental approval unless it is documented for the exact model.
Installation Guide
For safe and consistent installation, follow the instructions supplied with the product and the applicable electrical safety procedures.
Confirm compatibility. Check the cable conductor cross-section, cable outer diameter, cable construction, and required joint arrangement. Make sure the M15 is suitable for the intended cable and operating conditions.
Isolate the power supply. Installation must be carried out by qualified personnel after the cable has been safely de-energized and verified as isolated.
Prepare the cable joint. Prepare the cable ends and conductors using the appropriate jointing procedure. Keep the work area clean and follow the relevant electrical installation requirements.
Position the sponge strip and housing. Arrange the sponge strip around the designated joint area as instructed, then position the joint within the PP shell.
Prepare the resin. Mix components A and B according to the supplied instructions. Observe the specified ratio, mixing procedure, working time, and safety precautions.
Pour the resin. Fill the designated housing area as directed, taking care to follow the product's instructions for resin placement and sealing around the cable entries.
Apply the tape and close the cover. Complete the wrapping and assembly steps specified in the guide. Ensure the shell and cover are properly fitted.
Allow the resin to cure. Keep the assembly undisturbed for the specified curing period before handling or putting the cable into service. Follow the product documentation for inspection and commissioning.
Installation details may vary according to cable construction and the applicable electrical standards. The supplied product instructions take priority over this general guide.
