After assembly all the bars are wrapped together with polyester tape. The result is an insulation system that is virtually impervious to the stress of normal operation. The insulation system is tested after assembly with 2500 volt for one minute. This test is intended to confirm the integrity of the in- sulation system and helps ensure the highest qual- ity bus duct possible. All the insulation materials are rated as class H (minimum) non-flammable hence no internal fire barrier is needed.

Electric Power AP1000 Design Control Document 8.3 Onsite Power Systems 8.3.1 AC Power Systems 8.3.1.1 Description The onsite ac power system is a non-Class 1E system comprised of a normal, preferred, maintenance and standby power supplies. The normal, preferred, and maintenance power supplies are included in the main ac power system. The standby power is included in the onsite standby power system. The Class 1E and non-Class 1E 208/120 Vac instrumentation power supplies are described in subsection 8.3.2 as a part of uninterruptible power supply in the dc power systems. 8.3.1.1.1 Onsite AC Power System The main ac power system is a non-Class 1E system and does not perform any safety-related functions. It has nominal bus voltage ratings of 6.9 kV, 480 V, 277 V, 208 V, and 120 V. Figure 8.3.1-1 shows the main generator, transformers, feeders, buses, and their connections. The ratings of major ac equipment are listed in Table 8.3.1-3. During power generation mode, the turbine generator normally supplies electric power to the plant auxiliary loads through the unit auxiliary transformers. The plant is designed to sustain a load rejection from 100 percent power with the turbine generator continuing stable operation while supplying the plant house loads. The load rejection feature does not perform any safety function. During plant startup, shutdown, and maintenance the generator breaker remains open. The main ac power is provided by the preferred power supply from the high-voltage switchyard (switchyard voltage is site-specific) through the plant main stepup transformers and two unit auxiliary transformers.
