The opportunity that presented itself was the integration of the exterior rigid insulation board into the enclosure assembly to act not only as insulation but also as the primary sheathing and, in certain areas, as the drainage plane and vapor control layer.
A cable sheath also protects passerby and workers by limiting the chance of direct contact with an energized cable.
Sheathing can include one or more layers of insulating material and weatherproofing. Considerations in sheath design include the amount of energy the cable carries and where it will be used. The cables in Figures 1 to 3 have only plastic jackets.
The purpose of the jacket or sheath is for mechanical protection. If the sheath is solid metal, it also protects the cable from water ingress. The plastic jacket mechanically protects the cable and slows the ingress of water. Keep in mind that no plastic material will hermetically seal a.
Instructions. The covering under sheath is exposed about 2 cm length at one end of the cable so that the negative polarity shall be applied to it.; The conductive layer on outer sheath shall be removed about 20 cm wide at a distance of 30 cm from both ends of the cable.; The positive terminal of the DC source is connected to a copper band wound on the conductive layer of the sheath.
