greenspun.com : LUSENET : Elevator Problem Discussion : One Thread

Hi there I have had Old Dynaglide jobs in the past with power line conduits running in hoistway and you can hear power feed wires vibrating in the conduits, conduits acting like a bell and ringing in the building, any fixes for existing conduits, some guy mentioned filling pipes with sand to deden the noise. I know that a new hot setup is to use large diameter romex for power feed wires instead of multie single wire pulls. the romex wires are all together and its quiet. any fixes for old conduit power feeds. This is a common problem reusing existing feeds and changing from gen jobs to static drive. Jim
