FOREWORD

This

document

KOC

Standard

for

Low

lnduction

Motors

{KOC-E-O10)

is

intended

to

provide

minimum

requirements

f or select¡on,

manuf

acture and

operation

of

electrical motors

of

44A

Volts

to

be installed

at

KOC Facilities

in

Kuwait.

This

Standard

has

been

approved

by

the

Standards

Team

in

consultation

with

the

Standard Technical

Committee

(STC)

for

use

throughout

the corporate

Engineering

and

operational functions

of

Kuwait

Oil Company

(K.S.C.).

This Standard

sets out to

achieve the

following

objectives

To

provide

technical

guidance

for

selection

of

Low Voltage

lnduction

Motors

with

a view

to

achieve

safety,

uniformity,

quality,

reliability

and

efficiency

in

an

economical

manner.

b)

To maintain the

KOC requirements

of

safety

and

protection

to the

personnel,

plant

and

environment

established

by KOC's

Fire & Safety

Regulation,

Health,

Safety

& Environmental

Management

System

(HSEMS)

and

H&E Guideline.

c)

The

Data Sheets

have been

included

to set

out the

minimum

requirements

which will

also

act

as a checklist

to

ensure

that

all the

features for

design,

construction,

testing,

inspection,

installation

and

operation

of

Electrical

Motors

of

Low

Voltage rating.

Feed back
