Flooding compounds for telecommunications cables. Such flooding compounds contain a polymeric filler and a branched olefinic fluid. The branched olefinic fluid has an average of at least 1.5 methine carbons per oligomer molecule and at least 40 methine carbons per one thousand total carbons. Additionally, the average number of carbons per molecule in the branched olefinic fluid is from 25 to 200.

A method for forming an interconnect structure includes forming a patterned layer over a substrate, the patterned layer having an opening therein. A dielectric material is filled in the opening. The dielectric material has a precursor and a solvent, the solvent having a boiling point temperature greater than a precursor cross-linking temperature. A thermal treatment is performed on the dielectric material to form a dielectric layer.

Embodiments of the present disclosure relate to a power equipment and method for providing the same. Embodiments of the present disclosure relate to a power equipment. The power equipment includes a high voltage part, a low voltage part, and an insulation oil adapted to impregnate the high voltage part and insulate the high voltage part from the low voltage part. The insulation oil is partially filled with polymer particles with a lower thermal expansion coefficient than the insulation oil. According to embodiments of the present disclosure, the degree of expansion of the insulation medium can be reduced in a cost-effective way.
