Abstract: An easily shatterable dielectric insulating material is provided for junction boxes and other locations where it is desired to break the insulated material when it is necessary to intervene for modifying the junction. The insulating material, which has the good properties of good adherence to the electrical components regardless of temperature and which may be cast at ambient temperatures, comprises at least about 50 % by weight of coal tar pitch based on the total composition as well as a crosslinkable resin, a reactive diluent and a resin-hardening agent.
