CURRENT CARRYING CAPACITY
The Current rating given in the tables are based on the following
assumptions.
a) Maximum Conductor Temperature
|
-
|
70o C
|
b) Thermal Resistivity of Soil
|
-
|
150o C cm/w
|
c) Thermal Resistivity of PVC
|
-
|
650o C cm/w
|
d) Ground Temperature
|
-
|
30o C
|
e) Ambient Air Temperature
|
-
|
40o C
|
f) Depth of Laying (to the highest point of the cable laid direct in round or to
the top surface of ducts)

Some of the key areas that we focus on while undertaking retail research are:
- Understanding the actual requirement of a customer
- The customer behavior, their needs, habits, preferences, etc.
- What are the main motivators and barriers at retail points
- Optimizing the point of sale (POS)
- Role of displays to the customers, and Interactions of the sales teams
The following are the retail research that we conduct:
- Retail measurement services and retail audits
- Intercept surveys
- Mystery shopping
- Shop-Alongs
- Competitive Research
