PROBLEM TO BE SOLVED: To provide an arc-extinguishing insulation material molding excellent in heat resistance, strength and arc-extinguishing performance, and producible by a simple facility and process.SOLUTION: An arc-extinguishing insulation material molding 5 includes a crosslinked polymer as much as 50 mass% or more which contains a constitutional unit derived from at least one kind of an olefin-based monomer. The olefin-based monomer contains at least one kind of a cross-linking cycloolefin-based monomer which is a compound having a plurality of double bonds between carbon atoms in a molecular structure in aliphatic compounds each containing a carbon ring structure having a double bond between carbon atoms.SELECTED DRAWING: Figure 1 |
