- Crosslinked polyethylene insulated, PVC sheathed cables are utilized widely in both home and business due to their ability to withstand heat, carry heavy weights without damage, and be resistant to water and chemical spills.
- The Bureau of Indian Standards (BIS) ensures that all electrical cables meet the IS 7098 (Part 1): 1988 regulation and these cables are safe, reliable, and manufactured according to Indian law.
- The long-term performance of these cables can be guaranteed only through the appropriate testing of materials used in the production of XLPE PVC cables, including thermal ageing, insulation resistance, and elongation.
- Since there may be a delay in the tender approval process if any part of the electronic documentation submitted for BIS certification is missing or incorrectly prepared, expert guidance is very beneficial for manufacturers.
- BIS certification not only provides manufacturers with the ability to demonstrate adherence to regulations, but also offers manufacturers greater credibility when it comes to participating in government tenders and on a large scale with industrial projects.
Introduction
Crosslinked Insulated PVC Sheathed Cables are a great choice for wiring in factories, businesses, and homes. They really stand out because they can handle heat well, are super strong, and don’t get messed up by water or chemicals.It’s not just about making great cables; they also need to meet the BIS certification requirements under IS 7098 (Part 1): 1988. This is a must if we want to sell them legally in India and be considered for tenders.A lot of manufacturers really struggle with figuring out all the specific testing, paperwork, and factory checks needed to get that BIS approval.Take this cable maker in Gujarat, for example. They had a real headache with incomplete test reports, and it actually slowed down getting those government tender approvals.They got certified, which really boosted their market standing, all because they made sure their processes met BIS standards.These BIS-certified cables, with their special crosslinked insulation and PVC covering, really help to make sure things are safe and dependable. They also meet all the rules, which is great for manufacturers because it helps them stay ahead of the competition.Getting certified isn’t just about staying out of trouble legally; it also really helps open doors for government work and big industrial projects.
What is IS 7098 (Part 1) : 1988 ?
The Standard IS 7098 (Part 1): 1988 specifies the requirements for Crosslinked Polyethylene (XLPE) Insulated, PVC Sheath Cable with a Rated Voltage up to 1100V as per Indian Standards and is also used as the basis of design for these types of cables and manufacturers must meet this standard in order to obtain certification from the Bureau of Indian Standards (BIS) and to comply with Indian Laws.
Key Points
- Voltage Rating: States the maximum voltage rating (up to 1100 V) of cables intended for low voltage applications.
- Insulation & Sheathing: Consists of XLPE insulation and PVC outer sheath providing resistance to temperature and chemicals.
- Testing Requirements: Covers electrical testing (e.g., continuity, earth fault), thermal resistance testing, insulation resistance testing, elongation testing, etc.
- Safety & Performance: The goal of the standard is to make sure that the cables will withstand short circuit situations, mechanical load, and fire.
- Compliance & Certification: A mandatory document to get BIS certification, to submit a bid/offer, and to demonstrate compliance to the market in India.
Why is BIS Certification Mandatory
BIS (Bureau of Indian Standards) certification is an obligatory requirement for a variety of electrical products in India, including Crosslinked Polyethylene Insulated PVC Sheathed Cables. This certification is a guarantee that the cables conform to the IS 7098 (Part 1): 1988 standard. The sale of non-certified cables in India can result in legal prosecution, disqualification in tenders, and even pose a danger to users.
Key Points
- Legal Compliance: Indian regulation requires that IS 7098 (Part 1): 1988 compliant cable is a must for compliance with Indian law.
- Safety Assurance: The cables serve to provide assurance that the cables are compliant with insulation, fire resistance, and electrical performance.
- Tender Eligibility: Compliance with BIS certification is a requirement for participation in Government Tenders & Large Industrial Tenders.
- Market Credibility: BIS Certification provides a means for manufacturers to develop trust with their distributors, engineers, and end users.
- Quality Verification: BIS certification ensures that all materials, design, and manufacturing of the cable have undergone stringent BIS testing.
