Which conductor insulation is known to be oil resistant?

The conductor insulation known to be oil resistant is MTW (Machine Tool Wire). MTW insulation is specifically designed to withstand exposure to lubricating oils and other industrial fluids, making it suitable for use in environments where it may come into contact with such substances. MTW is constructed with a thermoplastic insulation material that provides excellent flexibility and durability, allowing it to perform well in applications involving machinery and equipment where oil presence is common.

In contrast, THHN is a type of insulation primarily used for building wire and may not offer the same level of resistance to oils. XLPE (cross-linked polyethylene) has good chemical resistance but is not explicitly specified for oil resistance as a primary characteristic. PVC (polyvinyl chloride), while widely used for various electrical applications, tends to have limitations regarding exposure to oils and chemicals compared to MTW. Understanding these properties helps in selecting the right insulation type for specific operating conditions.
