NKS, as a power cable accessories manufacturer, has long been dedicated to the R&D, production, and service of power cable accessories, committed to providing stable and reliable low-voltage insulation, protection, and connection solutions for global customers.
Ⅰ. Categories of Power Cable Accessories
1. Low Voltage Heat Shrink Tubing
Low voltage heat shrink tubing is a heat-shrinkable sleeve used for cable connections and insulation protection, suitable for low-voltage power systems.
2. RMU Test Tooling for Type-C Casin
Type-C Casin RMU test tooling is specifically designed for testing and maintaining Type-C Casin ring main units.
3. RMU Test Cable
The RMU test cable connects test tools to ring main units for conducting various electrical tests.
4. Transformer Accessories
Transformer accessories encompass components for transformer installation and maintenance, such as bushings and cooling systems.
Ⅱ. Performance of Power Cable Accessories
1. Materials and Weather Resistance
Heat-shrink tubing typically utilizes high-quality polyolefin materials, offering excellent electrical insulation, abrasion resistance, chemical resistance, and moderate UV resistance, suitable for both indoor and outdoor environments. Materials for RMU test tools and test cable brackets emphasize mechanical strength and durability to withstand on-site vibration, temperature fluctuations, and routine maintenance demands.
2. Heat Shrink Characteristics
Supports multiple shrink ratios (e.g., 2:1, 3:1) and initial diameter options. After shrinking, it conforms tightly to the cable's outer diameter, providing uniform wall thickness and effective sealing. Shrink temperature and speed are controlled within design specifications, ensuring controllability and safety during field use.
3. Electrical and Safety Performance
Features high dielectric strength, low leakage risk, and stable volume resistivity to effectively isolate and protect terminal and connection areas in low-voltage distribution systems. Meets industry-standard requirements for protection ratings and flame retardancy, ensuring controlled fire risk.
4. Mechanical Protection and Durability
Heat-shrink tubing delivers outstanding mechanical protection against abrasion, wear, and moisture ingress. RMU test tools and test cable trays emphasize structural strength and shock resistance for long-term field durability.
5. Quality and Certification
Manufactured under stringent processes and raw material controls, products comply with mainstream environmental and safety standards like RoHS, enabling global procurement and deployment across diverse regions.
Ⅲ. Selection Recommendations
1. Select Based on Diameter and Shrink Ratio
When choosing heat shrink tubing, first measure the outer diameter of the area to be covered. Then select the appropriate product based on the required shrink ratio and remaining coverage length. Prioritize series offering multiple diameters and shrink ratios to ensure uniform compatibility across different sections of the same project.
2. Material and Performance Matching
In humid, hot, or chemical environments, prioritize materials with enhanced chemical resistance and temperature tolerance to ensure long-term insulation and protection. For areas requiring frequent maintenance, select solutions supporting re-shrinkability or higher durability.
3. Compatibility and Installation Ease
Select sleeves and tools compatible with existing cables, connectors, and terminations to ensure tight fit with outer diameters, wall thicknesses, and connector interfaces. Prioritize products featuring coating, shrinking, and cooling processes that facilitate field operations.
4. RMU Tool and Bracket Selection Principles
RMU testing tools need to fit the equipment and test needs. Brackets must think about the wiring layout at the site, the weight of the cables, and how they are mounted. This helps keep the cables tidy and easy to maintain after they are put in place.
5. Certification and After-Sales Support
Choose products that have the right certifications and warranties. This makes sure they are reliable in the long term and have tech support. As a power cable accessories maker, NKS always focuses on quality control and after-sales service. When buying, check with suppliers about delivery times, how much they can customize, and what tech support they offer.
Ⅳ. FAQ
1. What electrical scenarios are the heat-shrink sleeves in this category primarily suited for?
They are used for insulation, end termination, and wire harness protection in low-voltage cables. Common applications include distribution cabinets, equipment connection points, and field wire harness branching areas. Material and process selections enhance insulation performance, mechanical protection, and IP ratings, making them suitable for indoor and outdoor environments.
2. What exactly is RMU Test Tooling? How does it differ from test cable trays?
RMU Test Tooling typically refers to test tool kits for Ring Main Unit systems, facilitating on-site wiring testing, location identification, and diagnostics. Test cable trays are structural components that support and organize test cables and harnesses, ensuring stability during field management and testing processes.
3. Can heat-shrink tubing or RMU tools be customized?
Customization is often possible (e.g., outer diameter, color, material grade, marking methods) to meet specific project requirements. Please contact NKS customer service directly with your specifications regarding dimensions, performance, certifications, and delivery timelines.
