Suitable for 33kV AC three-phase systems, designed using double-layer cold-shrink silicone tube with built-in stress cone to distribute the electric field evenly, local discharge capacity ≤ 10 pC; The connection of conductors is carried out by crimping, and the copper tube is suitable for cable cross-sections from 50 to 1000 mm².

Conductor Connection: Uses crimping or welding technology to securely connect two cable cores, which ensures good electrical conductivity between conductors, reduces contact resistance and minimizes energy loss. The insulating layer is made of silicone rubber, which has excellent insulating properties and corona resistance. It can withstand 24 kV voltage, preventing current leakage and short circuit.

Definition: It is a device installed in the middle of a 20 kV power cable line and used to connect two cables to ensure continuous transmission of electricity. The base material, ethylene propylene rubber, performs functions such as insulation, sealing and mechanical protection.

Porcelain support insulators are made of porcelain and are a device installed between conductors of different potentials or between conductors and grounding elements, capable of withstanding voltage and mechanical load. There are different types of insulators with different shapes. Although there are significant differences in the design and appearance of different types of insulators, they all consist of two main parts: insulating components and connecting fittings.

220KV Composite Column Insulators are high voltage insulation equipment made of silicone rubber as the core combined with fiberglass rods and metal accessories, specially designed for power transmission lines and substations.

220 kV, suitable for high-voltage 50 Hz three-phase AC transmission systems, ensuring long-term outdoor operation. The core is made of epoxy fiberglass and the protective shell is made of high temperature vulcanized silicone rubber, reducing weight by 45-50% compared to porcelain.

110 kV, suitable for high-voltage transmission and conversion systems of three-phase alternating current with a frequency of 50 Hz, ensuring long-term outdoor operation. The rod core is made of glass fiber reinforced resin, and the protective skirt is made of high temperature vulcanized silicone rubber, which is 50% lighter than porcelain and resistant to salt fog, ultraviolet radiation and chemical corrosion. Sealing the ends of the rod using the crimping method prevents moisture from entering the contact area of ​​the rod core.

110 kV, suitable for high-voltage 50 Hz three-phase AC transmission systems, ensuring long-term outdoor operation. In typical applications, the rod core is made of glass fiber reinforced resin and the protective skirt is made of vulcanized high temperature silicone rubber, reducing weight by 50% compared to traditional porcelain. The technology of crimping the ends and double sealing eliminates the risk of breakdown of the connection between the core and the shell.

66 kV, suitable for three-phase high voltage AC transmission systems with a frequency of 50 Hz. The design consists of a fiberglass rod and a silicone rubber protective umbrella, which is 50% lighter than porcelain and resistant to UV radiation and salt spray.

35 kV, suitable for high-voltage overhead lines of three-phase alternating current with a frequency of 50 Hz. Composite crossbar: fiberglass rod and protective skirt made of silicone rubber, weight reduced by 60%, high impact resistance, hydrophobicity: the surface energy of silicone rubber is low, which allows maintaining high insulation in dirty conditions (the flashover voltage increases by 2 times when dirty).

Featuring a conical or cylindrical design, it serves as crossmember support and insulation, replacing traditional metal/wood crossmembers, reducing support height and simplifying design. Main materials include electrical porcelain and silicone rubber composite, and the grooved surface increases creepage distance and prevents fouling.

33 kV, suitable for three-phase power lines and 50 Hz AC distribution systems, ensures long-term outdoor operation.
