Sodertite Terminations


Sodertite terminations are high quality, factory sealed cable terminations designed for maximum reliability. They feature exclusive metal-to-porcelain soldered joints which eliminates the need for gaskets and reduces installation time. Since their introduction in 1940, Sodertite terminations continue to prove the superiority of their design in an increasing number of field installations. The terminations will accept low pressure oil and gas filled cables as well as all extruded dielectric and paper insulated single and three conductor cables on distribution systems up to 46kV. Sodertite terminations are designed and tested in accordance with IEEE-48, 1975 standards for Class 1 terminations.

Features:
  • Maximum external insulation - The highest grade, wet process porcelain provides excellent mechanical strength and electrical characteristics. The large diameter, petticoat design combined with an external conducting glaze between the bottom petticoat
  • Reliable stress control – Stress relief cone kits consisting of insulating tapes and shielding braid are available as an insulating medium depending upon the application.
  • Gasketless sealing system – Special metal-to-porcelain soldered joints eliminates the need for gaskets throughout the termination. Spun copper wiping sleeve and hood provide maximum mechanical strength and positive sealing surface.

Vertical style aluminum or bronze clamped-on brackets are standard for single conductor units rated to 46kV. Cast aluminum horizontal style brackets are standard for single conductor units rated 69kV. Three conductor terminations have mounting lugs welded to the body of the termination. Flange style units incorporate either clamped-on or brazed-on mounting flanges. Bracket and flange insulators are available.

Copper solder style connectors are standard. Aluminum or copper compression style connectors are available.

Various clamp and bus style copper aerial lugs are furnished as standard. Silver or tin plating is optional. Protective rainshields are available for over the aerial lugs to increase insulation between phases if required.

Hand taped stress relief cones effectively control electrical stresses in the cable. Various kits consisting of insulating tapes and shielding braids are available depending upon the cable construction and voltage ratings.

Compounds are a high dielectric strength filler material used in terminations, cable heads, cable boxes and cable joints. An ideal compound should be chemically inert, adhesive and tacky; have low melting point to permit flow into all unoccupied space before solidifying, low moisture absorption, low dielectric loss, high dielectric strength and high flash and fire point for personnel safety. The selection of the proper compound for a particular installation depends upon: 1. Cable type and kind of insulation 2. Operating voltage and temperatures 3. Cable system elevation differentials (PILC cable only) Types of Compound NOVOID "A" - a medium soft asphaltic base compound recommended for use in most termination and cable head (switch or box) installations at 38kV or below. NOVOID "C" - a medium hard asphaltic base compound recommended for use in terminations and cable heads for application in hot climates or hot exposure at voltages up to and including 38kV. NOVOID "X" - a hard resin-base, oil insoluable compound recommended for use in terminations, cable heads and joints where migration of the cable-tape impregnant may be a problem. There are temperature limitations. NOVOID #224 - a heavy polybutene base compound recommended for use in terminations, cable heads and joints for polyethylene and EPR insulated cables. NOVOID "9A" - a very soft asphaltic base compound recommended for use in spreaderhead installations up to 38kV where the compound must be very fluid to rise up in lead or copper tubes. The lower part of the spreaderhead may be filled with NOVOID "X" to provide a barrier to help prevent migration of the NOVOID "9A" down into the cable. NOVOID #219 - a medium viscosity oil recommended for use as a "flushing compound" for building cable splices or terminating where such "flushing" is required. It may also be used as a filling compound in terminations and and joints on solid type paper insulated cables where oil filled accessories are desired. OZITE "B" - a medium soft asphaltic base compound recommended for use in terminations or cable heads.
