产品概述 Product Overview

全绝缘屏蔽铜管母线，实质就是利用铜管作导体、外敷绝缘的一种母线产品。在国外被称之为 " 管形电缆 " 。全绝缘屏蔽铜管母线具有大电流，目前载流量可以达到 12000A ，高机械强度、良好的绝缘、适用范围广等特性，所以被越来越多的客户认可和接受。

在国外，此类产品已经有几十年的运行历史和经验，而国内由于进入此领域时间较短，以及技术研发能力，绝缘材料的局限等多方面原因，目前生产、应用主要集中在 0.4KV —— 35KV 电压等级的产品。

Fully insulated shielded copper tube busbar is essentially a busbar product that uses copper tubes as conductors and external insulation. It is called "tubular cable" abroad. The fully insulated shielded copper tube busbar has high current, with a maximum current carrying capacity of 12000A, high mechanical strength, good insulation, and a wide range of applications.

Therefore, it is increasingly recognized and accepted by more and more customers. In foreign countries, such products have decades of operating history and experience, while in China, due to the short time of entering this field, as well as limitations in technology research and development capabilities and insulation materials, production and application are mainly focused on products with voltage levels of 0.4KV to 35KV.

结构特点 Structural Features

载流量大，集肤效应低，功耗低。 绝缘铜管型母线是一种空心导体，具有大的表面积，在导体表面上均匀的电流密度分布以及低集肤效应系数。 与多个矩形导体相比，它具有相同的负载。 在流动状态下，高压绝缘管型母线的交流电阻很小，因此母线的功率损耗很小。

良好的散热条件，低温上升和高压绝缘管形母线是空心导体，在新项目的天然绝缘铜管汇流排应用中，汇流排的内径风道可形成热空气对流。 散热条件较好。

截面系数大，机械强度高。 由于导体为管型，因此截面系数大，机械强度高。 可以大跨度排列，同时减少母线支架的数量。 在短路电流为50kA 的情况下，Φ100×5mm 铜管型母线的悬浮跨度为9米，母线可以由母线支架支撑，母线跨度可以达到13米。

高电绝缘性能。 高压绝缘管形母线采用密封屏蔽绝缘方式，壳体接地电位为零。 屏蔽绝缘管型母线电场分布均匀，电绝缘性能强，耐候性好。

强大的抗震性和简化的安装。 高压绝缘管型母线可直接固定在钢结构框架或混凝土支架上，可省去墙套和支柱绝缘子，抗震能力强。

母线结构简洁，布局清晰，安装方便，免维护运行。

绝缘材料具有较高的耐热性，耐老化性和较高的绝缘性能。 绝缘管形母线的主要绝缘材料是聚四氟乙烯，可在-250℃〜+ 340℃下工作。 它具有出色的电气性能和化学稳定性。 低损耗，阻燃，耐老化，使用寿命≥ 30年。

不受环境干扰，可靠性高，维护工作量低。 高压绝缘管型母线被覆盖绝缘，内部无凝露，消除了外界水分，粉尘等因素的影响，可靠性高。 高压绝缘管形母线采用单机密封和屏蔽绝缘，接地可靠，可以避免短路故障，可靠性高，维护量少。

High current carrying capacity, low skin effect, and low power consumption. Insulated copper tube busbar is a hollow conductor with a large surface area, uniform current density distribution on the conductor surface, and low skin effect coefficient. Compared to multiple rectangular conductors, it has the same load. In the flowing state, the AC resistance of the high-voltage insulated tube busbar is very small, so the power loss of the busbar is very small.

Good heat dissipation conditions, low temperature rise, and high voltage insulated tubular busbars are hollow conductors. In the application of natural insulated copper tube busbars in new projects, the inner diameter air duct of the busbar can form hot air convection. The heat dissipation conditions are good.

Large cross-sectional coefficient and high mechanical strength. Due to the tubular nature of the conductor, it has a large cross-sectional coefficient and high mechanical strength. Can be arranged over a large span while reducing the number of busbar supports. In the case of a short-circuit current of 50kA, the suspended span of the Φ 100 × 5mm copper tube busbar is 9 meters, and the busbar can be supported by the busbar bracket, with a busbar span of up to 13 meters.

High electrical insulation performance. The high-voltage insulated tubular busbar adopts a sealed shielding insulation method, and the grounding potential of the shell is zero. Shielded insulation tube type busbar has uniform electric field distribution, strong electrical insulation performance, and good weather resistance.

Strong earthquake resistance and simplified installation. High voltage insulated tubular busbars can be directly fixed on steel structure frames or concrete supports, eliminating the need for wall sleeves and post insulators, and have strong seismic resistance. The busbar structure is simple, the layout is clear, the installation is convenient, and maintenance free operation is required.

Insulation materials have high heat resistance, aging resistance, and high insulation performance. The main insulation material for insulated tubular busbars is polytetrafluoroethylene, which can operate at temperatures ranging from -250 ℃ to+340 ℃ . It has excellent electrical performance and chemical stability. Low loss, flame retardant, aging resistant, with a service life of ≥ 30 years.

Not affected by environmental interference, high reliability, and low maintenance workload. The high-voltage insulated tubular busbar is covered with insulation, with no condensation inside, eliminating the influence of external factors such as moisture and dust, and has high reliability. The high-voltage insulated tubular busbar adopts single machine sealing andshielding insulation, reliable grounding, can completely avoid all short-circuit faults, high reliability, and low maintenance.
