Flexible Electrical Conduit, WP-S1-1 series is manufactured with stainless steel strip by continuous wound in square lock profile. The size range of this series of flexible tube is ID 3.5~16.1mm. It is featured with excellent flexibility and its miniaturized diameter makes the tube be light and also pressure resistance. That offers benefit for deployment in complex or narrow spaces. The bare electrical flexible conduit can be directly used in a controlled environment. For those locations with splash or higher humidity, electrical flexible conduit with plastic jacket is recommended. That offers not only waterproof but also fire retardant. As for the demand of high abrasion resistance or preventing the interference of microwave or static electricity in the environment (EMC shielding), flexible electrical conduit with metal mesh braiding is the proper one to choose.
