Cable Terminations
Cable terminations are used to connect cables to power transformation equipment, switchgear, or overhead lines, serving as the entry or exit point of a cable system. Their primary function is to establish an electrical connection while providing reliable insulation and protection, thereby preventing moisture ingress and mitigating electric field concentration. Based on the operating environment, terminations can be classified into indoor and outdoor types; according to voltage levels, they are categorized into medium-voltage, high-voltage, and ultra-high-voltage terminations.
Cable Joints
Cable joints are used to connect two sections of cable and serve as critical components for ensuring the continuous operation of a power line. Common types include straight joints and branch joints, used respectively for extending a line or creating a line branch. These joints must possess excellent insulation recovery capabilities and mechanical strength to withstand the electrical and thermal stresses encountered during long-term operation.
Cable Branching Devices
Cable branching devices are primarily used for the splitting and merging of cable lines, and are commonly found in power distribution networks. They enable a main trunk cable to be tapped into multiple branch lines, or allow multiple separate cables to be converged into a single line. These accessories are typically manufactured using materials with superior insulating properties to ensure safe operation, even within complex cabling environments.
Other Auxiliary Accessories
In addition to the main categories mentioned above, cable systems also utilize various auxiliary components, such as cable seals, stress control elements, mounting brackets, and protective sleeves. These accessories primarily serve to enhance the mechanical fixation, moisture and dust protection, and electric field distribution of the cables, thereby ensuring the overall cable system operates with greater stability and reliability.
