Solid State Decoupler (SSD) for pipeline flanges by Dairyland Electrical

MTT Mounting Kit

Mounting the SSD or OVP2 to a flange can be accomplished via drilling and tapping the edge of the flange for a 5/16-18x1” or M8-1.25x20mm fully-threaded stud with jam nuts, or by pin brazing an M8x16 stud to each flange. Verify that the dimensions of either of these mounting arrangements are suitable for the flange before ordering. For mounting using tapped holes and studs, specify DEI part number MTT-516 for the 5/16” threaded studs, or MTT-M8 for the M8 threaded studs.

     Finish: Nickel Electroplated
     Thickness: 0.094"

MTS Mounting Kit

If mounting via pin brazed studs is desired, mount the device by using a M8x16 stud pin brazed to each side of the flange. The MTS kit provided by DEI includes “L” brackets, nuts, bolts, washers for each side of the flange. DEI does not supply the M8 stud kit or ceramic sleeve needed for this installation. Please order these parts from the manufacturer / distributor of the pin brazing equipment being used. Verify that the dimensions for this mounting arrangement are suitable for the flange before ordering.

MTL Lead Kit

Connection of an SSD or OVP2 normally uses #6 AWG insulated leads with compression terminals. Each lead has a factory installed compression terminal on one end with the other lead end left unfinished for cutting to the shortest feasible length during installation. (The required 5/16" bolts, nuts and washers to attach the leads to the device are furnished with each decoupler.) The standard lengths are 12 inches (300mm) and 36 inches (900mm).

Specify part number MTL-6-12 or MTL-6-36 for a set of two conductors with 12" or 36" lengths, respectively. For custom lengths, specify MTL-6-"X" and specify the units for "X." If a terminal is required for the unfinished end of the lead, contact DEI.

Note:  For any model with an AC fault current rating equal to or greater than 2 kA or for use with a Gradient Control Mat, two leads per terminal are required. If one set of leads is to be connected to a DEI furnished Gradient Control Mat, then the lead-to-mat connection will be thermit welded. See DEI information on Gradient Control Mats for connection details.

Hex Coupling Nut

Pin brazed studs are a convenient mounting method for the model SSD, attaching the decoupler to a pipe wall. Decoupler terminal connections can be made using insulated conductors, however total length should be minimized to limit the inductive over-voltage effects from lightning. One method of limiting conduction path length when also using 8mm pin brazed studs is the DEI Hex Coupling Nut, which attaches one SSD

36" Fiberglass Pedestal

Where a free-standing enclosure is desired for the Dairyland  PCR or SSD, the 36" fiberglass pedestal is ideal. Requiring no foundation or mounting structure, the pedestal is installed by partiallying burying the lower one-half in the soil. Cable entrance is via the open bottom area of the lower one-half, which is ideal for AC mitigation applications. The padlockable hasp prevents unauthorized access.
