Cold Shrink Cable Termination Kit

Cold Shrink Cable Termination Kit for 10kV–35kV XLPE Cables

Avantar's Cold Shrink Cable Termination Kit is available for medium voltage XLPE power cables rated 10kV, 20kV and 35kV. Each kit is a one-piece assembly of silicone rubber combining insulation, stress-field regulation and environmental sealing. No heating tools or open flame needed for installation, which facilitates work on site and requires less equipment. The kit contains the main tube, stress cone, sealing parts and all installation accessories. Products are in conformity with IEC 60502, IEEE 404, CE, RoHS certification can be provided.

Key Product Features

The kit body is produced from silicone rubber with stable dielectric characteristics across a wide range of operating temperatures. This makes it the appropriate solution for long term exterior installations in humidity, UV and salt-spray conditions.

The integrated stress control geometry is used to control electric field concentrations at cable ends. A consistent stress grading at this step reduces the risk of partial discharge and premature insulation breakdown at the termination.

Continuous sealing structure around the cable termination prevents moisture infiltration, dust and environmental contamination. This sealing technology is also very ideal for use in switchgear rooms indoors and outside substation termination locations.

Technical Specifications

Application Scenarios

Here are some common deployment situations where the reliability of medium-voltage cable termination is very important.

Substations and switchgear rooms: Indoor terminations connecting XLPE cables to medium-voltage switchgear or transformer terminals where consistent electrical performance is required.

Distribution of industrial power: 10kV to 35kV power lines in factories and plants, where installation without tools cuts down on planned downtime during maintenance windows.

Renewable energy projects: Solar and wind installations where outdoor cable terminations face extended UV and weather exposure throughout the project lifetime.

Underground cable systems: Urban infrastructure and tunnel projects where moisture sealing at the cable end is critical to long-term cable integrity.

Power on a construction site: both temporary and permanent power systems that need to be put together quickly and without special tools.

Custom Design Options

Avantar supports OEM and ODM customization for project-specific requirements. Standard catalog kits cover 10kV, 20kV, and 35kV voltage grades for XLPE cables.

For projects with non-standard conditions, available customization options include:

• Enhanced sealing configuration for coastal or high-humidity environments with elevated salt-spray resistance
• Non-standard assembly configurations for cables with unusual cross-sections or special insulation geometries
• Special packaging for tender project requirements or large infrastructure contracts
• Voltage-grade adaptation to match specific grid specifications in the target market

To begin a customization request, send your project technical specifications or drawings to our team. We will confirm design parameters and the production timeline before proceeding.

How to Specify?

Making sure of the following details before making an order will help pick the right Cold Shrink Cable Termination Kit for your project.

Step 1: Check the voltage grade. Find out if the cable system works at 10kV, 20kV, or 35kV. This figures out the right shape for the stress cone and the thickness of the wall of the silicone tube.

Step 2: Make sure you know the type of cable and its cross-section. All of these kits are made for XLPE-insulated power cables. Tell us the cross-section of the cable in millimetres so that we can get the right kit size.

Step 3: Confirm the installation environment. Say whether it will be used indoors or outdoors. Outdoor terminations near the coast or in areas with a lot of industrial pollution may need the stronger sealing configuration.

Step 4: Confirm the amount and the shipping needs: Most models have a MOQ of 10 sets. Lead time is usually between 7 and 15 working days. After technical approval, custom kits need 20–30 working days.

Quality and Certifications

Manufactured to international standards as follows: IEC 60502 for medium-voltage cable accessories, IEEE 404 for North American medium-voltage applications, CE for European market access, RoHS for environmental compliance.

Every export shipment is including installation instructions, hardware supplies, certificate of origin and IEC/CE test reports. These materials are available for inspection throughout the procurement and tender submission.

If the purchase is for big scale infrastructure, the customer can ask for a factory video inspection of finished goods or use third party inspection organisations like SGS, BV or TUV etc., before shipment.

Why Source from Avantar?

Since 2012, Avantar has been supplying electrical connection and power infrastructure components across the world. And the manufacturing base is in Guangdong, China, with core assembly, component matching and final quality inspection all done in-house.

Ship from Guangdong via water or by air. We also operate with EXW, FOB and other typical trading terms. When a project requires design updates, direct manufacturing cooperation implies no intermediate sourcing layer and shorter technical communication cycles .

First time purchasers might try trial shipments in small quantity for evaluation in the field before scale buying.

FAQ

Q: What is a product, and when is it the best choice for a job with medium voltage?

A: The product is a full cable end accessory that protects the end of an XLPE medium voltage wire from damage, handles stress fields, and seals the connection to the outside world. It can be used instead of on-site heating tools when they are not available or when speed and consistency of installation are important. The silicone rubber mix works well in a wide range of temperatures and might be able to handle being outside without extra protection.

Q: Do you make things or sell things?

A: The company Avantar is a manufacturer direct. We do the core assembly, matching of parts, and final quality inspection all in-house in Guangdong. This way, if you have a technical question, it goes straight to the manufacturing team without going through a third party.

Q: Do you work with projects that have unusual needs?

A: Yes. There are also choices for better sealing in salt-spray-prone coastal areas, non-standard assembly configurations for certain cable sizes, special packaging for contract submissions, and changing voltage grades. Send us your project specs or technical drawings to start the assessment process. After technical proof, it takes 20 to 30 working days to make a custom kit.

Q: What certifications and quality documentation do you possess?

A: Factory is produced according to IEC 60502, IEEE 404, CE and RoHS. The certificate of origin and IEC/CE test reports are supplied with each export shipment. Third party inspection for major project tenders can be arranged via SGS, BV, TÜV or a buyer nominated agency.

Q: What's the MOQ and lead-time for orders?

A: The standard MOQ is 10 sets per model. Standard catalogue goods ship between 7-15 biz days. Custom kits will take 20-30 working days to process from the date of design approval. Shipping by sea and air are both options.

Q: How can I evaluate product quality before placing a large order?

A: You can try a small amount for field testing before placing a large order, see all the certification documents, ask for a video inspection of the finished items at the factory or use SGS, BV or TÜV to do a third party pre-shipment inspection.
