10 FOOT DUCT SECTIONS

Standard duct sections are 10 feet in length. Casings for Park PIug-In Duct consist of two identical formedsteel halves. The two steel halves, when bolted together for the complete outside housing and also provide the exclusive scarf-lap feature. This permits two separate duct sections to overlap each other 12 inches to make interlocked joint. The scarf-lap joint provides extremely high rigidity and strength.

Park Plug-In Duct is available in 2-pole, 3-poIe and 3 phase, 4-wire construction. The middle bus bar is ommitted from 3-pole plug-in duct when 2-pole is required. All other construction details for 2 and 3-pole duct are identical.

All Park Plug-In Duct casings are of 14 gauge steel. Duct components are painted with an attractive gray enamel.

PARK NON-SEGREGATED PHASE BUSWAY

Park bus runs are complete lines of non-segregated phase bus duct designed for inter-connecting groups of metal-enclosed or metal-clad switchgear, power transformers or other related equip- ment. Bar type, with aluminum or copper conductors, is available in 600 volt, 5 and 15 kV classes. All conductors are individually supported on insulating members. Non-Segregated
Phase Bus
15 kV-5000 Amp Outdoor Bus with Cover Removed
All necessary equipment -- connection flanges, wall entrance seals, transformer and/or equipment taps, elbows, offsets, wall supports, splicing materials, terminal connectors -- is included to make a complete installation. The bus duct is designed, manufactured and tested in accordance with ANSI Standard C37.20.

Features

Custom Engineered
Your non-segregated phase busway is specifically designed to suit the requirements of your installation.

Low Installation Cost
All manufacturing and assembly procedures requiring skilled labor are factory performed. Field installation requires only placing the bus sections on the supports, bolting the splices, and connecting the ends to the apparatus terminals.

High Basic Impulse Insulation Levels
The basic impulse level of the bus duct is equal to or greater than that of the associated switchgear or other equipment.

  • Compact and lightweight
  • Maximum dependability
  • Factory assembled
  • Sturdy, rigid construction
  • Clean, attractive appearance

Applications

Available in a wide range of ratings to allow proper application for a variety of installation conditions. Park bus runs can be applied in both indoor and outdoor service.

A complete line of bus sections, including the following, is available:

  1. Terminating sections for transformers and switchgear.
  2. T-taps and Y-taps.
  3. Off-sets and elbows.
  4. WaIl entrance seals.

Bar Type Bus Duct

The bus duct conductor is available in either tin-plated, full round edge, type #110, flat copper bars or electrical conductor grade aluminum alloy #6101-Tel tin-plated per the "Alstan" process. Ducts may be specified in voltage classes of 6OO volts, 5kV and 15kV with current ratings to 6000 amperes as standard. Standard bus bracing is 75 kA at 600v, 60 kA at 5 kV and 60 kA at 15kV.

With the exception of the 600 volt class, all phase bus work is insulated with flame retardant Noryl insulation tubing. Tubing splices are tape insulated to meet the required voltage of the application. All bus joints are dry type, utilizing standard insulating materials.

All bus work is supported on molded, flame retardant, glass- reinforced polyester supports to meet the momentary withstand requirement of the location . Post type, ceramic bus supports are also available as an option. If an insulated neutral is required, it is necessary to modify the housing.

Where splice plates are required, they are equal in cross section to the main bus. All bus joints are made with one-half inch zinc plated steel grade 5 hardware.

BUS HOUSING

The indoor bus is enclosed in a ventilated housing. Outdoor bus is totally enclosed and gasketed, and equipped with space heaters. The top and bottom covers are removable to provide easy access to the bus.

Painted aluminum, or painted steel housings are available in current ratings through 2000 amps. Above this current, only aluminum enclosures are supplied Where a bus duct pases through a wall from indoor to outdoor, a weathererproof seal with a vapor barrier to prevent the passage of vapors is provided.

Both indoor and outdoor bus runs are supplied in unbroken sections as specified by the purchaser, up to a maximum of 30 feet.

Space heaters are mounted inside the outdoor housings to prevent condensation. They are 500 watt, 230 volt heaters wired to a 120 volt source. With this arrangement each heater will produce approximately 125 watts which prolongs the life of the heater element. They are spaced approximately every seven feet along the length of outdoor bus run. They are wired to the switchgear when the proper circuit is available, otherwise the wiring is terminated in a junction box of connection to the customer's source. This box is normally located on the side of the duct, inside the building, just beyond the wall flange.

BUS SUPPORTS

Trapeze-type hanger bars for every ten feet of bus are available as part of the assembly, on indoor installations, to support the bus runs. Wall brackets for vertical or horizontal mountings, and self-supporting bus runs are also available. Outdoor ducts supports are provided by purchaser, unless specified at time of quote. One support for every ten feet of duct is required.

ACCESSORIES

A complete line of elbows, tees, terminations for transformers and switchgear, phase transpositions, expansion or earthquake joints, wall entrance seals, flexible connectors, bushing stud connectors and terminal enclosures is available.
