In this paper, the insulation system of HVAC / DC high voltage insulated cable is reviewed. First, the current insulation type and its transmission system are compared. Then, the technical requirement of low loss and high capacity is discussed as the modern requirements from the transmission system. Finally, Ultra-high electric field of insulation, and in accordance with the design of power transmission system, including the focus, including PPL insulation and HPTE(PLASER) insulation, including two types of latest forms of insulation and its main application. The full paper revolves around the insulation form of the transmission cable system, which is discussed by the transmission voltage and capacity, and explains the latest application prospect of different insulation forms.

In this work eight different crude biocatalysts together with six Lewis and three Bronsted acids were used for asymmetric aldol reactions of aromatic, heteroaromatic, cyclic, and acyclic six ketones and eleven aldehydes. Optimum reaction conditions were determined by changing temperature and enzyme, ketone, aldehyde, solvent, cofactors types, amounts, and ratios. PPL (porcine pancreatic lipase) of animal and AL-AN (amano lipase A from Aspergillus niger) of fungal origins were the best ones and compared with each other. CoCl2 was the best cofactor and catalyzed the enzymatic aldol reaction better than without cofactor. CoCl2 was not used before for enzymatic aldol reactions. The method in this study, using crude biocatalysts (PPL or AL-AN) and CoCl2 in acetonitrile-water was found as an conventionally useful biocatalytic way for asymmetric aldol reaction and has given better ee values than in the literature.
