Winding wires for submersible motors play a crucial role in ensuring efficient motor operation
under submerged conditions. These wires are coated with Polyester and Polypropylene, as this
type of material offers excellent insulation. The material used for manufacturing the wires
reduces the risk of electrical failures during their operation.
To ensure the safety of these wires, the Bureau of Indian Standards has outlined the
requirements under IS 8783 (Part 4/Sec 3): 1995. This Indian standard ensures that the wires
meet the quality and performance parameters. The companies manufacturing winding wires
must obtain a license to sell their products in the market.
What is IS 8783 (Part 4/Sec 3): 1995?
This is the Indian Standard for polyester-insulated wires used in submersible motors. In order to
ensure that the wires are safe for reliable operation, a few requirements must be met. As per the
BIS (Bureau of Indian Standards),
wires are:
- Tested for heat resistance
- Checked for electrical conductivity
- Verified for insulation thickness
- Assessed for shrinkage and heat shock
Eligibility for PP Insulated Winding Wires BIS License
BIS authorisation under IS 8783 (Part 4/Sec 3): 1995 is required for businesses involved in
manufacturing, importing, or supplying polyester insulated winding wires in India.
Applicable to:
- Manufacturers (India) - Must get BIS approval if the submersible pump motor wires are
covered under QCO.
- Foreign Manufacturers - Need certification to export the product to India.
- Importers/Brand Owners - Must ensure that the winding wires are BIS-certified before
selling.
- Sellers/Distributors - Should only sell certified Polyester & PP Insulated Winding Wires
for Motors.
Testing and Inspection Requirements
To ensure reliable performance of Insulated Winding Wires, the Bureau of Indian Standards
outlines the minimum requirements under IS 8783 (Part 4/Sec 3): 1995. This certification
ensures that manufacturers maintain consistent product quality. It also ensures that the wires
provide effective insulation and stable performance under submerged operating conditions.
The BIS testing parameters and quality checks for the submersible motor cable are listed below:
BIS Approval for Polypropylene Insulated Winding Wires
The BIS Authorisation process ensures that the motor winding wire meets the required
standards for proper and efficient operation. This process is set by the Bureau of Indian
Standards (BIS) and includes the following steps:
- Online Registration: Manufacturers register on the BIS Manak portal by submitting company, factory, and product details. Foreign manufacturers must appoint an Authorized Indian Representative (AIR).
- Testing at BIS-Approved Laboratory: Product samples are tested in BIS-approved laboratories for material, dimensional accuracy, and surface finish.
- Application Submission: The application is submitted along with test reports, technical documents, and factory details. Foreign manufacturers must also submit AIR-related documents.
- Factory Inspection: BIS officials inspect the manufacturing units to verify the production process, safety measures, and quality control system.
- Grant of BIS License: If all the above requirements are met, BIS grants the certification license under Scheme-I.
- Use of ISI Mark:After approval, the manufacturer can use the ISI mark on the product with a CM/L number, confirming that the product meets BIS standards.

Marking Requirements & License Validity
Marking Requirements
When a manufacturer obtains BIS Approval, the ISI Mark for Elastomer Cables must be clearly and permanently marked on its packaging or on the product. In addition to the ISI Mark, essential details must be printed such as the manufacturer’s identification, licence number (CM/L), etc. This ensures the product meets all quality and safety standards. More details are mentioned below:
| Requirement | Details |
|---|
| ISI Mark | Indicates that the product is BIS certified and conforms to standards |
| Standard Number | IS 8783 (Part 4 / Sec 3) : 1995 |
| CML Number | Certification Marks License (CML) number issued by BIS |
| Manufacturer Details | Name of manufacturer or registered trademark |
| Batch / Date | Batch number, heat number, or manufacturing date for traceability |
Note: Marking is typically applied using durable stamping, tagging, or permanent printing to ensure clear identification during handling, storage, and transportation, as per BIS marking requirements.

Conclusion
IS 8783 (Part 4/Sec 3): 1995 specifies the standard requirements for winding wires used in
submersible motors, particularly polyester and polypropylene insulation winding wires. This
standard outlines the quality and performance criteria that the manufacturers must meet for safe
usage. It also gives some criteria relating to the electrical characteristics to ensure effective
performance while being underwater.
Getting a certification from the Bureau of Indian Standards would enable the manufacturers to
meet the legal requirements. It also ensures that only compliant products are permitted for sale
in the market. EVTL India provides expert assistance to manufacturers in obtaining BIS
