NKS POWER Premoulded Joints: The Premier Choice for Electrical Connections
Reliable cable connection solutions play a major role in getting electrical systems stable and secured. NKS POWER has taken upon itself the commitment to the global supply of high-quality, high-performance pre-molded cable joint products as a selectively focused manufacturer of Premoulded Joints. Our joints are engineered from advanced material through progressive methodologies intended to ensure excellent electrical characteristics and mechanical support. This product range dynamically matches the requirements of different voltage levels and application scenarios after rigorous testings that prove certification in operation under complicated environments. From high-voltage transmission lines to medium and low voltage distribution systems, these offer solid ground for safe and efficient operations.
Ⅰ. Introduction to Premoulded Joints
Premoulded joint are inlaid with stress control parts in the insulation body in advance in the factory production, no interface exists, through the stress control parts to effectively solve the problem of stress concentration at the cable shield cut. Using silicon rubber high resilience, high temperature resistance and strong aging resistance, and cable insulation to adopt interference combined design. This ensures that the interface between cable insulation and accessories is closely combined without internal creepage. In order to meet the four types of pollution environment, and design the external insulation of the accessories. 35kV prefabricated cold shrinkage power cable accessories are suitable for the connection of 21/35kV,26/35kV single/three core XLPE power cable.
Product execution standards: IEC60502.4, GB/T12706.4

Ⅲ. Product Categories
1. Heat-Shrink Joints
This joint utilizes specialized heat-shrink material that melts upon heating to fill the connection area of the cable joint, forming a tight electrical and mechanical bond. Heat-shrink joints offer outstanding waterproofing and chemical corrosion resistance, making them particularly suitable for underground cable systems and humid environments. Installation is simple and quick, requiring no complex tools or equipment, significantly reducing construction time. Additionally, heat-shrink joints possess good flexibility, accommodating cable bending and vibration to ensure long-term stable operation.
2. High-Voltage Preformed Cable Joints
Addressing the specific demands of high-voltage power systems, NKS POWER has developed 36kV preformed cable joints. Manufactured using high-performance insulating materials through precision molding processes, these joints withstand electrical stresses under high voltage, guaranteeing insulation reliability in high-voltage environments. The design of the 36kV preformed cable joints prioritizes compatibility with cables, forming secure electrical connections and seals after installation to effectively prevent moisture and impurity ingress. With a compact structure and precise dimensions, they are suitable for high-voltage transmission lines in urban power grids and power supply systems for large industrial enterprises, providing safe and reliable connection assurance for high-voltage power transmission.
3. Medium and Low Voltage Preformed Cable Joints
NKS POWER offers 15kV preformed cable joints suitable for use in medium and low voltage power systems. Electrical performance may generally be assumed as typical; however, more attention has been paid to ease of installation and actual cost of the joint. It has a simple structure with small dimensions thus making it possible to install within restricted spaces. Stable electrical connection is assured by this joint in medium-low voltage environments due to reduced contact resistance hence minimized energy loss through appropriate structural design and material selection..Usage of such a product in commercial buildings, residential complexes, and industrial facilities can be an efficient yet reliable solution for distribution as well as utilization connectivity.
Ⅳ. Advantages of Premoulded Joints
1. Premium Materials and Advanced Manufacturing
NKS POWER uses top-grade materials in making Premoulded Joints that lead to excellent performance and long life. Together with modern processes and automatic production, we ensure the same quality for each joint that protects the steady working of power systems.
2. Stringent Quality Control Systen
