    2.1.2  绝缘导线：导线的型号、规格必须符合设计要求，线槽内敷设导线的线芯最小允许截面：铜导线为1.0mm2；铝导线为2.5mm2。
    2.1.3  螺旋接线钮：应根据导线截面和导线根数，选择相应型号的加强型绝缘钢壳螺旋接线钮。
    2.1.4   LC安全型压线帽请见3.2.1.5有关内容。
1 Scope
    This technology is applicable to drying chamber according to the electrical wiring works obviously.
    2 construction preparation
    2.1 Material Requirements:
    2.1.1 Plastic trough: the bottom of the tank, tank cover and annexes, it is a flame-type PVC plastic extrusion, forbidden to use non-flame retardant type material processing. Use plastic trunking should be selected according to design type, the appropriate setting product specifications. The installation site ambient temperature of not lower than -15 ℃, the oxygen index of not less than 27%. Groove above the inner and outer edges smooth without thorns, should not be distorted, such as deformation of Alice side. And a product certification.
    2.1.2 Insulated wire: wire models, specifications must meet the design requirements, groove laying wire line core within the minimum allowable section: copper wire is 1.0mm2; aluminum wire is 2.5mm2.
    2.1.3 Spiral Connection button: wire cross section and the conductor should be based on root number, select the appropriate type of reinforced steel spiral wire insulation button.
    2.1.4 LC-safe pressure line caps, see 3.2.1.5 the content.
