Abstract

[Problem] To provide a twist-resistant cable with improved durability. [Solution] A twist-resistant cable provided with an assembly comprising multiple intertwined electric wires, a tape member covering the outer periphery of the assembly, and a sheath member sheathing the assembly covered by the tape member, wherein the sheath member has a tensile yield stress of 3.5 MPa to 10 MPa, and the intertwining direction of the assembly is the same as the wrapping direction of the tape member.

Abstract

An electric heater (1) having a linear heater body (20) housed in a heat transfer tube (10), wherein the heater body (20) has a folded section (24) in the heat transfer tube (10) so that a pair of ends (26a, 26b) of the heater body is lead out from one end of the heat transfer tube (10). The heater body (20) includes a heat generation portion (25) formed along a part of the heat transfer tube (10), and a lead portion (26) capable of electrically connecting the heat generation portion (25) to the outside of the heat transfer tube (10). The electric heater (1) can be inserted into a narrow space to provide local heating.
