摘要： A paper suitable for use as separator in an electrochemical cell, including at least 60 wt. % of an aramid fibril and at least 1 wt. % of an aramid fiber. The paper has a grammage of 5 to 100 g/m2, and the aramid fibril has a Canadian Standard Freeness (CSF) in a wet phase of less than 300 ml and a specific surface area (SSA) after drying of less than 3 m2/g. It has been found that a paper with this composition combines good electrolyte absorption and ion permeability with high stability during use, leading to a long lifetime for the electrochemical cell.

摘要： In the field of single phase HVDC converter transformers there is a need to reduce the creep stress arising on the surface of an insulation assembly within the transformer without adversely impacting on the manufacture of the transformer.
An insulation component (50; 80), for a limb of a HVDC converter transformer, comprises a component body (52) which has first and second ends (54, 56). An inner surface, that in use faces the magnetic core (12) of a limb (14, 16) of a HVDC converter transformer, extends between the first and second ends (54, 56). An outer surface (58), which lies opposite the inner surface, also extends between the first and second ends (54, 56). The outer surface (58) has a surface profile (60; 82) which extends between the first and second ends (54, 56) and that includes at least one raised formation (64; 84).
