奥尔巴尼项目计划在尼亚加拉莫霍克电力公司的电网中安装一条350米长的高温超导(HTS)电缆，在34.5千伏的电压下传输800个武器。该类型的电缆在一个低温恒温器中有3个高温超导芯，高温超导导线和屏蔽层使用Bi2223。这三个核心被安置在双SUS波纹管内，提供隔热。这些胶带是用一种新的创新烧结方法和可控过压(CT-OP)技术制造的。电气绝缘用的是聚丙烯层压纸(PPLP)。电缆将安装在长长的地下管道中。将在地下拱顶内制作电缆接头，将30米长的电缆与剩余的320米电缆连接起来。长期运行后，将用30米长的YBCO电缆取代原来的BI-2223 30米电缆。电缆两端的终端在低温容器中将有三个套管。为了验证设计，进行了典型的性能评估实验，如电缆弯曲测试、电压测试和故障电流测试。根据美国爱迪生照明公司协会(AEIC)关于35kV级电缆的规范，对一根5m长的电缆成功地进行了69kVAC和200kV冲击电压试验。该电缆将于2004年和2005年制造和安装，届时将开始长期运营。
The Albany Project plans to install a 350 m High Temperature Superconducting (HTS) cable in the power grid of the Niagara Mohawk Power Company to carry 800 Arms at 34.5 kV. The type of the cable has 3 HTS cores in one cryostat with Bi-2223 used for HTS conductor and shield layers. The three cores are housed within double SUS corrugated pipes which provides thermal insulation. The tapes are manufactured with a new innovative sintering method with controlled over pressure (CT-OP) technology. Polypropylene laminated paper (PPLP) is used as electrical insulation. The cable will be installed in long underground conduit. A cable joint will be made in an underground vault to connect a 30 m length of the cable with the remaining 320 m. The original Bi-2223 30 m cable will be replaced with a 30 m YBCO cable after long-term operation. The terminations at both ends of the cable will have three bushings in a cryogenic vessel. Typical performance evaluation experiments, such as cable bending tests, voltage tests, and fault current tests, have been conducted with sample cables to check the design. Voltage tests for 69 kV AC and 200 kV impulse were successfully applied to a 5 m cable in accordance with the Association of Edison Illuminating Companies (AEIC) code of 35 kV class cable. The cable will be manufactured and installed in 2004 and 2005, then, long-term operation will be started.
