- Color coding using a counting pair in each layer is applied. The counting pair conductors must be of different colors and must differ from the colors of other conductors. Each separate layer must have one conductor of red colour and one of blue. These two are placed side by side and called a counting pair. Other conductors must be white. The blue conductor is used to find the required one by counting from it. The red conductor is used to determine the direction of counting.
- The digital code is applied by printing. The colour of the digits must contrast with the main colour of the conductors insulation. The bottom of the digit must be underlined. The counting starts from 1, each conductor has a unique number.
- This cable type is used for transmission and distribution of power in electric installations with rated alternating voltage of 660 V or 1000 V and 50 Hz frequency. .
- Its laying has no restrictions of the difference in elevation along the cable route including its vertical sections.
- The cable is intended to operate in electric networks of alternating voltage with grounded or isolated neutral. Their time of operating in single-phase earth fault mode should not exceed 8 hours and the total operating time in single-phase earth fault mode does not exceed 125 hours per year.
- These cables are designed for laying of single cable lines in the cable installations and industrial premises. Bunched laying is allowed only in the outdoor electrical installations and industrial premises with just occasional presence of the maintenance staff. In that case a passive fire protection is required.

Frequently asked Questions
- How much do the VOLTA® cables and wires cost?
- The price depends on the product type and order volume. To get a relevant price list email your request to email@example.com. Our manager will send you a quotation as soon as possible.
- What products are there in stock?
- We use the Smart Warehouse concept. The system monitors the logistics of goods starting from receiving and storage to assembly and shipment. We know at any time how much cable and wire is available right then and how long will it take us to execute any order taking into account the finished products and raw materials in stock. Just leave your request at firstname.lastname@example.org.
- What are the payment terms?
- To start the order execution we need to get a prepayment from you which is calculated individually. We accept payments only via bank transfer. The invoice should be paid no later than 3 business days from the issuing date. If you have delayed the payment we will refund the money net of actual costs incurred.
- What time does it take to execute an order?
- It takes 3 weeks on average. Production time depends on a chosen product type, its features, and production load and can vary from 1 week to 2 months.
- What are the delivery options?
- We deliver loads up to 2 tons to the office of any shipment company in Smolensk free of charge within 5 working days from the payment date. Smolensk is a convenient logistic point located 400 kilometers to the West from Moscow along the Federal Highway M1. There are offices of various international shipment companies delivering to Europe or the USA such as PEK (First Forwarding Company), CDEK Express, DPD. You can also pick up your order yourself from our warehouse at the 5th kilometer of Roslavlskoe shosse.
- Can I get a 10-20 cm cable sample to make a decision about a purchase?
- Leave your request at email@example.com. If the cable you need is in stock we will send a sample at our expenses.
- Can I get technical advice from PC SEC experts?
- Leave your request at firstname.lastname@example.org. Our sales team consists of real techies: former factory workers, technology officers, and installers. Each of them is an expert in technical aspects of cable production and installation. The goal of our managers is not to sell at any cost, but to solve your specific task.
