This one-of-a-kind seismic slip joint was specially designed and fabricated by Stress Engineering Services for the San Francisco Public Utilities Commission. It is capable of accommodating nine feet of contraction, one foot of extension and an external bending moment of 55 kip-feet and shear of 32 kips. Tests proved it can fully contract in two seconds and is equipped with eight exterior chambers to receive the displaced water during a contraction.
Medium- and low voltage equipment specifiers can adopt digital twin technology to adopt a circular economy approach for sustainable, low-carbon equipment design.
Medium- and low voltage equipment manufacturers can prepare for environmental regulations now by using innovative MV switchgear design that eliminates SF6 use.
Using digital tools and apps for nearby monitoring and control increases safety and reduces arc flash hazards since electrical equipment can be operated from a safer distance....
