Where space and accessibility
exist, a wire mesh grid may be installed at floor level or overhead to supplement the above cabling network. Equipment enclosures and racks should be bonded to this wire mesh. The mesh should be bonded to structure at each point where structural members are accessible.
Both ends of shielded
cable shall be terminated to case or enclosure. Continuous peripheral bonding of the shield is best. Filters and TPDs installed for noise suppression and transient protection must be directly grounded to the enclosures of the protected equipment.
TPDs installed in distribution
frames and junction boxes must be terminated directly to the ground bus or to the mounting enclosure. The ground bus and the mounting enclosure must be bonded to the fault protection subsystem with minimum length conductors.
Application industry
It is widely used in metallurgy, oil and gas, glass manufacturing, aluminum, petrochemical, coal mine, paper and printing, textile printing, machinery, electronic manufacturing, automobile manufacturing, tobacco, plastic machinery, electricity, water conservancy, water treatment/environmental protection, municipal engineering, boiler heating, energy, power transmission and distribution, etc.
