INTRODUCTION TO MAC PRE-INSULATED

UNDERGROUND DISTRIBUTION SYSTEMS

This catalog has been designed as your guide to the various pre-insulated MAC Systems for low voltage underground distribution cable connections. These systems have been engineered to provide reliability, economy and versatility of installation.

A superior, time proven method for connecting low voltage underground distribution cables in manholes and vaults is the use of a pre-fabricated cable jOint system. Proper use of these systems provides a reliable, orderly arrangement of equipment and cables in a manhole. Versatility for future connections can easily be provided by selecting those items designed for expansion capability.

Many years ago, acceptable standards and designs were established for underground connection systems. The obvious advantages of this standardization are interchangeability of the parts made by various manufacturers, stocking of components, availability of product and ease of training personnel. MAC underground connection systems meet these standards and interchangeability requirements.

DESIGN CRITERIA FOR MAC UNDERGROUND SYSTEMS Although each type of product shown in this section is designed for specific customer service preferences, they all have several common features:

MAC CRAB SYSTEM

Economical Versatile Reliable Simplified Installation

A pre-insulated, multiple connection system at a single junction point. This system utilizes a common copper bus bar with tubular cross members used to form outlets on both sides. Factory applied HYDUR-N Insulation eliminates extensive hand taping under field conditions. Designed for installation of conductors by use of standard compression tools and dies.

MULTI-MAC SYSTEM

Essentially the same as a crab except this system utilizes mechanical installation of the conductor in a cable receptacle. A feature of this system is the abilityto quickly and easily make additions or changes to any arrangement.

LIMITERS

Limiters are designed to prevent damage to cable insulation due to a fault current. MAC Limiters should be used on all secondary cable junction points. Choosing the desired limiter for the rated cable insulation can assure isolation of a fault on the secondary before service interruption or damage can occur to other sections of the system.

2 of 40

MULTI-MAC A pre-insulated copper bus bar which has threaded outlets that accept cables by use of a mechanical clamping system consisting of three elements: Cable Receptacle, Nut and Cone.

The hexagonal copper bus bar has holes at each outlet position which are drilled and tapped to accept the threaded stud of the desired cable receptacle. After the cable receptacle is threaded into the Multi-MAC, the stripped conductor is inserted first into the nut and then the tapered compression cone. The conductor is then inserted (with nut and cone) into the cable receptacle and secured by tightening the nut. The connection can then be made watertight by using Type USS insulating sleeve with minor taping at both ends or by completely taping the connection. Proper installation provides a completely watertight joint.

Versatility 1) Unused outlets can be left plugged for future addition of cables

2) Quick and easy removal of installed cables

3) System expansion can be accomplished by jOining several Multi-MACS together by use of Type UCC Coupler

4) Cable sizes can readily be increased by choosing the proper cable receptacle, cone and nut assembly for the size required

AMPACITY RATINGS

Multi-MACS are rated at 1500, 2000, 2500 and 3000 Ampere capacity. This is based on the maximum current carrying ability of the cross section of the insert. Each individual outlet carries the full rated current capacity of the conductor connected to it. Arrange the cables as shown below, to avoid exceeding the insert rating. This arrangement allows that maximum current flows directly across the insert.

INSULATION

Our molded, HYDUR-EP insulation has been engineered to eliminate taping of the crotch area and is sufficiently thick to prevent sagging caused by insert weight or fault conditions. For details of Insulation properties, refer to Page 17.

ORDERING INFORMATION

1) Choose Multi-MAC type desired

2) Select proper ampere rating required within that type

3) Determine number of desired outlets

4) Choose cable range desired for each outlet

5) Choose proper cable outlet arrangement (Le.: outlet #1, "A"; all others "8", etc.)

The unique insulating feature of the MAC No-Tape Crab type CN assures water tight jOints when used on standard 500 MCM rubber neoprene cable.

As shown in the diagram below, the extra overlap of free rubber beyond the end of the cable socket forms a water tight fit over the cable insulation. The No-Tape Crab is installed in the same manner as the standard type CN. Simply roll back the outlet sleeve past the indenting posi­tions, compress the cable into place and roll the outlet sleeve back to original position. For added assurance of a water tight connection, a coating of rubber cement may be applied to the cable insulation before the outlet insulation is rolled to final position.

The No-Tape is insulated with HYDUR-N and neoprene coated. Supplied with all outlets sealed except one. Seal is removed by cutting the end cap off with a knife.

In 1951, MAC Products, Inc., developed a line of limiters for use on 265/480 volt A.C. networks for the protection of cable and bus circuits supplying power to concentrated loads.

The new design of our cable-to-cable limiter, Type EPl, is encased in rubber and is suitable for submersible operation. Interruption of currents in excess of 100,000 amperes RMS., at 480 volts across the limiter, is accomplished in accordance with our recommendations. Water is prevented from entering into the limiter construction itself and into the connected cable.

Where short circuit protection is needed from one-half of a cycle to a longer indefinite period, these limiters have proved adequate and economical. Where quicker protec­tive interruption of the circuit is required, other circuit breaker devices are recommended.

MAC 265/480 volt A.C. limiters are of such construction that they possess the heat capacity to absorb and radiate heat generated from the limiter without any injury to their insulation or to the cable insulation under normal load conditions. The quartz filling with the aid of a special deionizer assures reasonably low level noise performance. All these devices have been tested at several values of current between the "float" value at about 1800 amperes and in excess of 100,000 amperes, RMS, at 480 volts across the limiter section. Voltage and current relationships were maintained in test to produce maximum disturbance and violence on arc interruption. Oscillograms were taken at most test currents of 3,000 amperes and greater.

Reproduced below are three typical oscillograms of cur­rent and voltage relations on interruption of currents indicated at 480 volts across MAC limiters. The voltage was maintained at 480 volts because it is possible that this voltage would exist momentarily across a limiter in actual operation under fault conditions. Therefore, since MAC 265/480 volt limiters repeatedly interrupted currents from

1900 to over 100,000 RMS amperes at 480 volts and 5% power factor in numerous tests, we feel that all users of these items will be assured of satisfactory interrupting ability under more favorable service conditions. In actual­ity, they will satisfactorily interrupt much higher currents under actual operating conditions.

The type EPl limiter is designed for cable to cable connections under either dry or submersible conditions. The entire limiter is encased in a one piece, seamless molded HYDUR-N jacket which is resistant to water, oils or other contaminants. The NO-TAPE feature which is ef­fected by the overlap of the cable insulation by the HYDUR-N jacket, minimizes or eliminates the need for taping.

Designed for connection of cable to flat, the type Oll limiter lug is supplied with a removable boot molded of HYDUR-N. Mounting hole arrangements other than those shown on page 14 are readily available.

REDUCING ADAPTERS

Sizes not listed are available upon request. For adapters for use on ALUMINUM connectors consult factory.

Custom molded with Hydur-N, a high performance natural rubber compound and neoprene coated for added reisstance to corrosive elements, the CNA ser­ies of insulated aluminum crab joints satisfies the need for a reliable, fully insulated, multiple connector. The high conductivity all-aluminum internal element is of heavy duty design and all outlets are factory filled with Mactex inhibiting Compound. These compact crab joint connectors may be installed with standard compression tooling.

The MAR adapters are used to reduce the cable size of standard compression type connectors. Fabricated of soft, pure copper and hot tin coated for corrosion resistance, the MAR is designed for use with long double indent connec­tors. Installation is accomplished by inserting the adapter into the connector barrel, positioning the cable within the adapter, and compressing with standard tooling. For most sizes, the shape of MAR is as illustrated. However, some sizes are slightly different.
