Description

technical field

[0001] The invention provides a class 1E K1 cable insulating material for nuclear power, and also discloses a preparation process of the cable insulating material, which belongs to the technical field of special cables. Background technique

[0002] Nuclear power plant 1E cables refer to safety-level products of electrical system equipment that complete the emergency shutdown of the reactor; containment isolation, emergency cooling of the core, export of residual heat from the reactor, heat export from the containment of the reactor; The safety categories of nuclear power plant electrical system equipment are divided into three categories: K1, K2, and K3. Among them, K1 products are generally installed in the containment of nuclear reactors, and must still be able to perform their specified functions under normal environmental conditions and under SL2 (safety shutdown ground motion) loads and during or after accidents.

[0003] When the cable insulation mate...
