CONSTRUCTION OF LT PVC / 3 CORE XLPE CABLES
Underground cable is not a just a piece of conductor or link between two locations. It is electrical component that has an infinite value of resistance, capacitance, inductance and many factors such as number of joints over the total length. There are different type of LT cables such as PVC & XLPE (cross link Polyethylene) cables & HT cables such as Paper, Oil field paper, XLPE (cross link polyethylene) cables.
VARIOUS CABLES USED IN POWER DISTRIBUTION NETWORK
PVC cables Paper insulated cables Oil field paper cables XLPE (Cross Link Polyethylene) cables
These above cables are divided in two parts Low voltage (LT) cable and High voltage (HT) cables.Generally due to the less transmission losses and long life advantage XLPE cable are widely used in power networks.
WHAT IS A CABLE FAULT ?
A cable fault is any defect that affects its performance.A power distribution cable of any size, working voltage, insulation material etc. can develop following faults
Most common types of fault are
Contact Fault (Short circuit)
Break Fault (Open circuit)
Flashing Fault
Ingress of Moisture
Ground Contact Fault
However they vary so much that they take on a multitude of forms.
1. CONTACT FAULT
A short circuit fault between two cores or between core / coresand the metallic sheath. The fault resistance can vary from zero Ohm to few M Ohm
Core to Core Contact Fault
Core to Sheath Contact Fault
2. BREAK FAULT
This type of fault is also called as open circuit fault. One or all The cores of the cable break at a point, having infinite resistance between two ends. There can be cases when there is a measurable resistance across the gap or with adjacent metal.
3. FLASHING FAULTThe cable withstands insulation test up to some level, beyond which it flashes at a spot that acts like a spark gap.
4. INGRESS OF MOISTURE
Water enters into cable at some point of damage and remains inside it. It causes insulation breakdown at weak point.
5. GROUND CONTACT FAULTThis fault is also called as earth fault or sheath fault. Core or metallic sheath or armour of the cable comes in contact with mass of earth due to external damage.

INTRODUCTION OF POWER CABLE FAULT LOCATION
Before we proceed to the training of LT/HT cable fault location it is necessary to discuss about cable faults. Any defect, weakness, inconsistency that affects the performance of cable is called as cable fault. Fault occurs in a cable because of external interference, such as over load operation, external damages, manufacturing defects.No two faults can be identical with each other.Fault location of underground cable requires different equipments for conducting many tests depending upon the fault characteristic. These tests can be performed systematically to achieve thesuccess of cable fault location. The power distribution division of industry has also to undertake measures to repair all breakdowns within shortestpossible time.

UNIQUE CHALLENGES OF
SME’S IN INDIA
What is an SME category of Industry ?
It is a Small or Medium Enterprise with a Turn over between
25 Lakhs – 10 Crore
SME’s in manufacturing sector contribute significantly to the
Indian Economy. According to Small & Medium Business
Development Chamber of India, SME’s contribute to 45% of
nation’s industrial output, 40% of total exports, 95% of total
industrial units in the country & 8000 quality products for Indian &
International market.
Indian SME sector has emerged as a highly vibrant &dynamic sector of the Indian economy over last 5 decades.
Play crucial role in providing large employment at low capital
cost.Complementary to large industries as ancillary units.36 million units provides employment to 80 million people.
SME’s play a significant role in National development through
High development contribution to Domestic production.Significant Export earnings. Low investment requirements. Operational Flexibility.Location wise mobility.Low Intensive Imports. Capacities to develop Appropriate Indigenous Technology.Import substitution.Contribution towards Defense Production etc.
Clusters
Indian Manufacturing clusters have a strong footprint in the
economy. They account for 40% of nation’s industrial output &
35% of direct exports.
Govt. should encourage more clusters with a similar product
profile. For e.g. A cluster where SME’s manufacturing capital
goods such as Telemetrics can be grouped together in industrial
hubs in all states and their major industrial towns / cities.
Despite high enthusiasm & inherent potential & capabilities to grow SME’s face number of challenges.
Suboptimal scale of operations.Technological obsolescence.Supply chain inefficiencies. Domestic & International competition. Working capital shortages.Not getting trade receivables from large & Multinational Cos on
time. Insufficient skilled manpower.Change in manufacturing strategies & uncertain market
scenario.
SPECIFIC CHALLENGES FOR
TELEMETRICS
Our customers are Govt. utilities, public sector companies, Pvt.
Ltd. companies where payment terms are anywhere between
30 days to 90 days (for some customer like MSEDCL 120 days).
This leads to a cash flow contraction.Working capital requirements for large value orders are not
addressed. 100% advance is almost unheard of but we now insist on 50%
advance, 75% wherever possible to maintain cash flow. But this
is for a small pool of customers.Credit facilities from banks are subject to rigid, stringent & time
consuming procedures.While banks do need security before advancing credit / loans,
security needed is 100% which can be a problem for
entrepreneurs. Typically the loan advanced is 80% of value of
security.
Processing fees, Stamp duty, Visiting fees, Renewal fees are
additional to be borne by the SME. This involves long procedures, reevaluation of the security
every year leading to additional cost. ROI on loan/credit provided is 12.75% which is a huge burden
for the SME against 8% which bank offer on FD’s.W.e.f. 1st June CBDT has notified that for remitting suppliers
internationally, form 15CA / 15CB is required adding to the
convoluted process. Govt. announced sops for women Enterprises are not reflected
on the ground.For LC’s & BD’s, Bank charges intent of 12.75% making it
unviable. Bank commissions are extra for LC or BD.Even after long association of the industry with the particular
bank, loan/credit sanction taken 45-60 days after submission.
Uncertain nature of business, customized products, delayed
payment from customers means that our cash flow is always
stretched.
Suggestions for Improvement
Reduce documentation process & simplify it. Processing/Renewal charges can be waived off.Quicker loan approvals not more than 7-10days. Creation of a special SME cell not just physically but with a
different blue print with respect to approval of loan, rate of
interest, disbursement of loan, reducing of collateral
requirements based on a special SME Nodal Committee
report.Creation of a special SME Nodal Committee with a team of
experts that can evaluate the efficiency, reliability & credibility
of an SME unit.Consortium of banks to address issues of SME’s.
IT IS ONLY BY ADDRESSING ISSUES OF SME’S AT THE GROUND LEVEL CAN THE “ MAKE IN INDIA” CAMPAIGN SUCCEED.
