Welding Splice

Welding Splice

Product Description

The Welding Splice refers to a specialized type of cable splicing connector that utilizes welding technology to create a permanent, high-conductivity connection between electrical conductors. Unlike mechanical or compression splices, this method involves melting the conductor materials (typically copper or aluminum) to form a seamless metallic bond, ensuring minimal resistance and exceptional mchanical strength. The process often involves exothermic welding (thermite reaction) or precision arc welding techniques, resulting in a molecular-level fusion that withstands high short-circuit currents, corrosion, and thermal cycling. This solution is particularly valued in critical applications where electrical stability and longevity are paramount, such as grounding systems, high-current busbars, and infrastructure projects requiring ultra-reliable connections.

Designed for extreme environments and heavy-duty applications, welding splices offer unmatched durability and performance under stress. The exothermic welding process, for example, creates a connection that is inherently resistant to electrochemical corrosion and outperforms the base conductor in current-carrying capacity. These splices are often packaged as pre-assembled kits containing molds, welding materials, and igniters for field deployment. While requiring specialized training and safety protocols due to high-temperature operations, welding splices provide a maintenance-free, lifelong solution for power networks, industrial plants, and railway systems where failure is not an option.

Design Methods

• The conductor is melted at high temperature so that the ends of the conductor are fused into one, compared with crimping, there is no change in structural dimensions, higher tensile strength and other advantages. Suitable for 10-35kV cables.

• When the splice welding is completed, using the form of winding through high temperature vulcanization in order to restore the cable's inner semiconducting shield, insulation, outer semi conducting shield; metal shielding, steel tape, sheath in accordance with the installation of the ordinary way to restore.

• The welding splice can nearly restore the cable size in terms of dimensions and performs better in terms of waterproof performance, which is suitable for environments with relatively harsh conditions of humidity.
