定义
导体连接器是高压绝缘电缆终端中的关键部件,设计用于在电缆导体之间建立永久、低电阻的电气连接。它在极端的电气、热和机械应力下工作,保持完整性以防止电弧、过热和连接失效。其设计通常涉及压接、压紧或螺栓连接机制,以确保最佳表面接触和长期可靠性,适用于电力传输和配电系统。

工作原理基于在导体之间建立永久、高压的机械接头。这通过压缩(使用液压或机械工具将连接器套筒变形到导体上)、压接或螺栓连接来实现。施加的力破坏表面氧化物和污染物,允许纯金属与金属接触。这最大化了接触面积,最小化了电阻,并形成气密密封以防止氧化和湿气侵入,确保在部件寿命期内稳定的电气性能。
工作原理
The working principle is based on creating a permanent, high-pressure mechanical joint between conductors. This is achieved through compression (using hydraulic or mechanical tools to deform a connector sleeve onto the conductor), crimping, or bolting. The applied force disrupts surface oxides and contaminants, allowing pure metal-to-metal contact. This maximizes the contact area, minimizes electrical resistance, and creates a gas-tight seal to prevent oxidation and moisture ingress, ensuring stable electrical performance over the component's lifespan.
材料
高导电性铜合金(例如C11000电解韧铜)或铝合金(例如1350-H19)通常镀锡、银或镍以增强耐腐蚀性、减少氧化并提高导电性。绝缘部件可由高介电强度材料制成如硅橡胶、EPDM或热缩聚合物。

常见问题

What is the primary function of a conductor connector in a high-voltage cable termination?

Its primary function is to create a permanent, low-resistance electrical and mechanical joint between cable conductors, ensuring reliable power transmission while withstanding electrical, thermal, and mechanical stresses.

How does compression technology improve connector performance?

Compression technology deforms the connector onto the conductor using controlled force, creating a gas-tight, cold-welded joint. This maximizes contact area, minimizes resistance, prevents oxidation, and enhances mechanical strength, leading to superior long-term reliability.

What are the key material considerations for conductor connectors?

Key considerations include high conductivity (copper or aluminum alloys), corrosion resistance (often via tin or silver plating), mechanical strength, and compatibility with conductor materials to prevent galvanic corrosion and ensure thermal expansion matching.
