| 11. | An alternate less expensive and time-consuming construction method is using dry insulating material.
 
  | 
 | 12. | Compared to conventional insulating material, silicone can perform in far higher and lower temperatures.
 
  | 
 | 13. | Once begun, PD causes progressive deterioration of insulating materials, ultimately leading to electrical breakdown.
 
  | 
 | 14. | Doors, insulating materials, windows and beds also are badly needed.
 
  | 
 | 15. | The insulating material is typically made of solid polymers which have issues with degradation.
 
  | 
 | 16. | Because their motors are air-cooled, it is impractical to wrap them in sound-insulating material.
 
  | 
 | 17. | BPB's other products include plaster, insulating materials, fastenings, decorative wall covering and ceiling components.
 
  | 
 | 18. | Using a variety of configurations, two electrodes are separated by various dielectric insulating materials.
 
  | 
 | 19. | The insulating material of the substrate forms a dielectric.
 
  | 
 | 20. | PCBs, or polychlorinated biphenyls, were used as insulating material in transformers and other electrical equipment.
