Electrical accessories for power transmission systems and methods for preparing such electrical accessories

A coated electrical accessory energizable to facilitate distribution of power, the coated electrical accessory comprising:

• a bare electrical accessory, and
• a substantially inorganic and dried coating layer coating the bare electrical accessory, said coating layer exhibiting a solar absorptivity coefficient of about 0.4 or greater and comprising a binder and a heat radiating agent, the binder comprising from about 15% to about 65%, by dry weight, of the coating layer, and the binder comprising a metal silicate selected from the group consisting of sodium silicate, potassium silicate, lithium silicate, or combinations thereof;
• and
• wherein when tested in accordance with ANSI C119.4-2004, the operating temperature of the coated electrical accessory is lower than the operating temperature of the bare electrical accessory when the same current is applied.
